Troubleshooting

Why am I getting an “Incompatible mod set!” error?

There are a few versions of this error, but they all ultimately mean the same thing: You’re missing something another mod needs to work, or your mods are incompatible with each other.

Note: We understand that these error pop-ups are ugly, difficult to read and extremely confusing. While we haven’t had time to fix this in time for our first beta, we are planning on solving this problem and providing something that everyone can understand.

Missing dependency

The following errors mean you’re missing the Quilt Standard Libraries — please download them and add them to your mods folder or launcher mod list.

  • Dependency for mod ‘mod-id’ on fabric versions …
  • Dependency for mod ‘mod-id’ on quilt_ …

Any other dependencies listed similarly are other mods, and you’ll need to download them separately and add them to your mods folder or launcher mod list.

Incompatible mod versions

If the error specifies that a mod exists but isn’t valid for resolution, you have incompatible mod versions. You’ll need to double-check that all your mods are up-to-date and, if they are, contact the developers behind the mods that are causing problems.

Jar-in-jar resolution error

JiJ resolution error

If the error you’re getting looks something like this, then this is a problem with a mod you’re using — you should report it to that mod’s developers. The mod you’re looking for in this example has been circled in red above for clarity — in this case, the mod would be QuickCarpet.

My game is crashing. Why is this happening?

If your game is crashing, the most likely cause is a problem with a mod you have installed. It’s always worth trying to figure out if this is the case, and you can attempt to do so by following these steps:

  1. First, take a look at your latest.log - you can find this in the logs/ folder located within your Minecraft profile, which will likely be in your .minecraft/ by default.
  2. If you notice errors in your log referring to a specific mod, try removing it and see whether you can reproduce the error.
  3. You could also try using a binary search to track down a misbehaving mod - move half of your mods to another folder, and test the other half. If there’s no issue in that half, switch to the other one. Continue to split your mods in half and test each half until you’ve managed to isolate the problematic mod.

If this doesn’t help, or you have trouble reading the logs on your own, please feel free to drop into the #quilt-basic-support channel on The Quilt Community Discord server, and we’ll try to help you out. Please remember to provide your latest.log and any other relevant issue when requesting support!
