Issues getting my modpack to load

User Support

Ive been working on a modpack on fabric and decided to move over to quilt to see if it would work. It did not and it crashed saying it had an internal error and to post here. The full crash log is to big to post, so im not sure how to do that.

Could you post the full log? You might have an incompatible mod installed, like Decorative Blocks.

3

that would probably be it, I have that on the modpack, but do you have a link to something like a list of all known incompatible mods?

4

Not all, but most of them, yes: Mod Incompatibility Megathread - User Support - QuiltMC. Specifically for Decorative Blocks, though, there’s a fork by the same name on CurseForge, that works on Quilt and even 1.20+
