Fixing Mod Conflicts and Crashes

Mods are great until they aren't. If your server started crashing, players are getting errors, or vehicles are glitching out, you've probably got a mod conflict. Here's how to deal with it.

Signs of a Mod Problem

• Server crashes on startup
• Server crashes when a specific vehicle spawns
• Players crash when joining
• Vehicles look broken or have missing parts
• Console is spitting out errors

Step 1: Check the Console

Your Console tab is your best friend here. Look for error messages, especially:

• Lines with ERROR or WARN
• Crash stack traces
• Messages mentioning specific mod names or file paths
• Lua errors

The error message usually points right at the problem mod.

Step 2: The Toggle Test

If the console isn't obvious, isolate the problem:

1. Open the Mod Manager tab
2. Disable ALL mods (toggle them all off)
3. Restart the server
4. Confirm the server runs fine with no mods

If the server still crashes with no mods, the issue isn't a mod — check your server config or contact support.

5. Enable mods one at a time, restarting after each
6. When the problem comes back, you found your bad mod

It's tedious but it works every time.

Step 3: Dealing with the Problem Mod

Once you've identified the culprit:

• Remove it. Some mods just don't work in multiplayer.
• Check for updates. The mod might have a newer version that fixes the issue.
• Check compatibility. Some mods need specific BeamNG.drive versions.
• Look at the mod's comments/reviews. Other people probably hit the same problem.

Common Mod Issues

Outdated Mods

Mods built for older BeamNG.drive versions often break with updates. If a mod hasn't been updated in a while, it might not work.

Duplicate Vehicle Mods

Two mods that modify the same base vehicle will conflict. For example, two different "improved Gavril D-Series" mods can't coexist.

Oversized Mods

Some mods are huge (500MB+). They can cause:

• Long download times for players
• Memory issues on the server
• Timeout errors during connection

Map + Vehicle Conflicts

Rare, but some custom maps can conflict with certain vehicle mods. If you're getting crashes only on a specific map with specific vehicles, try testing them separately.

Prevention Tips

• Add mods in small batches. Don't dump 20 mods at once — add 3-4, test, then add more.
• Back up before adding mods. If something breaks, you can restore in seconds.
• Stick to well-rated mods. Mods with lots of downloads and good reviews are less likely to cause issues.
• Keep your mod count reasonable. More mods = more chances for conflicts. Quality over quantity.
