The arma reforger addon load error comes from broken or missing workshop mods, and a clean mod setup often restores normal loading.
What The Arma Reforger Addon Load Error Means
The message with kick cause code group 4 data and reason 5 addon load error tells you that the game failed to load one or more addons linked to your current scenario or server. The engine expects every listed mod to be present, up to date, and in the right order. When a dependency is missing, corrupted, or mismatched, the scenario stops and you land back on the menu instead of reaching the mission.
On PC the message often appears together with a long list of addons in the console log or crash window. Console players see a shorter line that still mentions addon load error and asks them to check the log. The text looks vague, yet the pattern is consistent enough that you can treat every addon load error as a mod health problem first and a game file problem second.
Quick Checks Before You Change Anything
Start with light checks so you do not break a setup that only needs a small nudge. Many players rush straight to a full reinstall and lose time while a simple refresh would have done the job. The goal in this phase is to confirm that your game can boot without any extra content and that basic network access works as expected.
- Reboot the device — Restart your PC or console so memory and cached processes tied to mods clear out.
- Launch the base game only — Start a simple official scenario with no workshop content or custom mods enabled.
- Test a low mod server — Join a lightly modded or fully vanilla server and watch for any addon load errors.
- Check storage space — Make sure the drive that holds the game and workshop data is not near full capacity.
If the game runs scenarios and servers with no workshop content, you know the core install is healthy. When the addon load error returns as soon as you pick a scenario that relies on custom mods, you can safely spend your energy on repairing the mod stack instead of chasing rare engine bugs.
Addon Load Error Fix Steps For PC And Console
Most fixes live inside the in game workshop and mod manager. Bohemia bug reports and Steam posts show that disabled or broken dependencies sit behind many addon load problems, even when the mod that appears in the list looks fine at first glance. The steps below walk through a safe way to tidy your mod set on both PC and consoles without losing the content you still use.
- Open the workshop mod manager — From the main menu go to the workshop section, then head into the list of installed mods or addons.
- Sort by health or warnings — Look for entries with missing dependencies, version warnings, or local errors and mark them first.
- Disable broken addons — Turn off mods that show missing links or that you no longer need for your current servers and scenarios.
- Remove abandoned mods — Unsubscribe from addons that have not seen updates in a long time and rarely appear in server mod lists.
- Restart the game after changes — Fully close Arma Reforger, then launch again so the mod set reloads from a fresh state.
Console players reach the same workshop screen through the main menu, sometimes under a dedicated mods tab. The layout differs, yet the principle stays the same. Disable content with broken links first, then cut down any mod that you no longer use. This trimmed list reduces the chance that a hidden dependency ruins a training mission or solo scenario later on.
Fixing Addon Load Problems On Modded Servers
When the error appears only on certain servers, your local files might be fine while the server mod list creates the mismatch. Public servers often rotate addons, move to fresh versions after patches, or carry one extra dependency that your client did not download correctly. A single missing piece triggers the same addon load error even if the rest of the pack sits in good shape.
Match the server mod list before you blame the game. Open server details, subscribe to the listed collection, let downloads finish, then restart and join again. A clean sync between server mods and your local workshop often removes addon load errors on that server.
- Update all workshop mods — In the mod manager, trigger updates for every addon tied to that server and wait for completion.
- Remove stray client mods — Turn off content that the server does not list to avoid conflicts and needless load time.
- Ask admins about required versions — Many groups pin a specific build, so confirm that your workshop pulled the same one.
- Capture a log snippet — If errors persist, grab the relevant part of the console or log file and share it in the server help channel.
If several players report the same addon load error on one server, the fault likely rests on the server side config or its workshop cache. In that case an admin may need to clear temporary folders, change the addon order, or remove a duplicated dependency in the server launch line. Your client side changes help, yet only a clean server setup removes the root cause for the whole group.
Clean Up Workshop Cache And Game Files
When trimming the mod list does not help, the next step is a deeper clean of local cache folders. Workshop downloads use hidden directories to store extracted addon data. A partial download, interrupted patch, or disk hiccup can leave stale files behind. The game then loads a mix of old and new content and trips over an addon that no longer matches the version expected by the scenario or server.
- Verify game files — On Steam or your chosen launcher run a file integrity check to refresh any damaged core game data.
- Clear local workshop cache — Delete or rename the workshop cache folders listed in the official help page for your platform.
- Re download core mods only — Subscribe again to the main addons you use daily instead of trying to pull your entire old list at once.
- Check antivirus or firewall rules — Make sure security tools are not blocking the game from reading or writing its addon folders.
On console the steps look slightly different. You may need to remove local save data or clear reserved space for the game, which forces a fresh pull of workshop content the next time you subscribe. Always read the console prompts so you do not wipe unrelated save data by mistake. When in doubt, back up saves or profile settings before a big reset of cached content.
A full reinstall sits at the end of this path, not the start. Only take that step if verification and cache cleanup fail, or if the error also appears on bare scenarios with no workshop content. At that point a clean install removes any chance that a leftover file under the game directory keeps feeding bad addon data into new sessions.
Spot Patterns In Addon Load Error Messages
The addon load error string looks short, yet the context around it offers useful clues. The game usually prints either a list of specific addons or a shorter hint about missing dependencies. You can treat that log text as a map that points you to the mod that deserves your time. The table below shows common patterns players report and the areas that respond best when you tweak them.
| Error Pattern | Likely Cause | Best First Step |
|---|---|---|
| Long list of addons after error | Old or broken client workshop data | Disable bad mods and clear cache |
| Error only on one server | Server mod list changed or uses new build | Match server mods and ask admins |
| Error in every custom scenario | Shared dependency missing across several mods | Update all mods and check dependencies |
| Error even with no mods selected | Core files or install corrupted | Verify files, then reinstall if needed |
Use these patterns as a guide, not strict rules. The exact text can shift between patches, and the way the console lists addons may change. Still, once you note whether the error sticks to a single server, hits only one scenario, or appears across the whole game, the path forward becomes much clearer and your fixes stay focused.
Keep Addon Load Errors Away After Later Updates
Arma Reforger receives regular patches and workshop creators push updates as well, so mod stacks move over time. A little routine care after updates saves you from another round of addon load error messages on the next game night. Treat your workshop library as a living list instead of a permanent collection that never changes or trims.
- Prune your mod list monthly — Remove content you no longer use and keep only the addons that fit your regular servers.
- Favor active workshop projects — Subscribe to mods with recent updates and engaged creators who track game patches.
- Read patch notes for mod sets — Many groups document which versions they run so players can sync their local setup.
- Back up config files — Save main server and client configs so you can restore a known good state if a fresh patch breaks something.
Once you treat arma reforger addon load error messages as signals from your mod stack instead of random crashes, they lose much of their stress. With a calm checklist and a habit of keeping mods tidy, you cut downtime, join sessions faster, and spend more of your game time on firefights instead of file hunting.
