How to fix Mod Conflicts

Fixing Mod Conflicts in Arma Reforger (TMG Ops Guide)​

Mod conflicts are the fastest way to break your server, crash your game, or bootloop your startup. Whether you're running realism packs, custom gear, or full-blown scenarios, this guide walks through how to diagnose and fix mod conflicts—cleanly.

What a Mod Conflict Looks Like​

• Server boots, then crashes mid-load
• Players get “Missing Mod” or “Failed to Download” errors
• Mods load out of order or override each other
• Scenarios fail to start or spawn broken assets

Step 1: Identify the Problem Mod​

• Check `modloader.log` in your server’s log directory
• Look for lines like:

Failed to load mod: BetterMuzzleFlashes
Reason: Missing dependency: WeaponCore

If you see “missing dependency,” “version mismatch,” or “mod not found,” you’ve got a conflict.

Step 2: Validate Mod Metadata​

• Go to `Documents\My Games\ArmaReforger\addons`
• Open `ServerData.json` inside each mod folder
• Confirm:
  • modId
  • name
  • version
• Compare against your server’s `config.json` mod list

If the mod ID or version doesn’t match, fix it manually.

Step 3: Clean Your Addons Folder​

If mods won’t download or load:

• Close the game
• Go to `Documents\My Games\ArmaReforger\addons`
• Delete all folders or just the broken ones
• Restart the game and re-download mods

Step 4: Fix Load Order Issues​

Mods load in the order listed in `config.json`. If one mod depends on another, it must come after it.

"mods": [
  {
    "modId": "WeaponCore",
    "name": "WeaponCore",
    "version": "1.0.0"
  },
  {
    "modId": "BetterMuzzleFlashes",
    "name": "BetterMuzzleFlashes",
    "version": "2.0.8"
  }
]

Reorder your list to match dependency chains.

Step 5: Check for Platform Conflicts​

If you’re running mods, console players cannot connect. Add this to your config:

"supportedPlatforms": [ "PLATFORM_PC" ],
"crossPlatform": false

Step 6: Use Known Fixes​

• Use Endless Conflict Fix if your scenario breaks
• Avoid duplicate mod names or IDs
• Don’t mix Workshop mods with local-only mods unless you know what you’re doing

Final Notes​

Mod conflicts are fixable. Validate your metadata, clean your folders, and keep your load order tight. If you’re stuck, post your `modloader.log`, `config.json`, and mod list. Tag TMG Manic.
