If your Arma 3 mods are corrupted, you can try the following solutions:
- Manually delete the affected mods and restart Arma 3. The launcher will then redownload all of the mods.
- If you are using the in-built launcher and mods are from Steam Workshop, you can open the mod in the list and select repair. If that does not work, unsubscribe from the mod, restart your PC, and then resubscribe to the mod.
- Restore the default legacy mods folder in the launcher to “C:SteamLibrarySSDsteamappscommonArmA 3”.
- Go to Steam>Settings>downloads and click Clear download cache. You will have to login to Steam on restart.
