My minecraft server running on 1.20.1 (fabric 0.14.21) crashed and from what i could tell by looking at the crash log it could be caused by lithium (lithium-fabric-mc1.20.1-0.11.2.jar). I don't know how to reproduce the bug, I had minecraft in the background and when I returned to it I saw that the server has crashed. I don't know how did that happen, but I was alone on the server and nobody was doing anything.

Here's the crash log:

The crash occured once again. I was standing in one place, not moving or doing anything and it happened out of nowhere

The crash report does not hint at lithium causing or being involved in this crash. I cannot tell from the crash report what the cause is, so you probably need to remove half of the mods at a time to find the mod that is causing this.

Maybe this mod helps find the issue https://www.curseforge.com/minecraft/mc-mods/uwrad/files

Oh alright, I thought there was a chance it could be lithium because it's the only mod name I could see there, sorry for wasting your time. And also thanks for this detector mod!
