Whenever I try to look up something in JEI it always ends up crashing due to something in Immersive Railroading.
The crash log shows something about a rolling rendering issue, but I'm not sure what it is exactly...

Also crash when searching JEI

This is an issue with the cache/universalmodcore folder. Deleting that should fix it, also underlying bug was fixed in the test builds
