[MC 1.18.1 / Fabric Loader 0.14.1] mcmmo crash due to NoClassDefFoundError: StructureManager

Looking at Issue #10 shows StructureManager as implemented, so I believe this is a bug. Changing mcmmo versions doesn't seem to help at all.

I tried multiple Fabric Loader versions from 0.13.3 up to 0.14.5 but the latest working version seems to be 0.14.1 since all later versions crash for me because of issue #345.

Has MCMMO ever worked with cardboard? I know I've tried a couple of times but i do believe every time I have its never worked but its never crashed the server on me.

The bug isn't specific to mcmmo. It occurs when a plugin tries to place a structure

[KP2048]

Or anything regarding structure manager

The problem is that the wrong version of paper API is downloaded and plugins that rely on a newer version shit their pants. This is only one of the bugs caused by this. See the issue I made that linked this one for another example

Some can be mitigated by manually placing a newer jar and renaming the file to match the original one, but this is not a fix and should be delt with properly

@MadByteDE you might be able to use Mcmmo if you do what I did above to get around this bug. Download the latest paper API jar and replace the jar in the libraries folder with the newer jar. But make sure the new jar has the exact same name as the old one or it won't be loaded properly
