Why i kept crashing at herb cave when there is players?

I dont know why but every time I enter herb cave that has players in it at the flower area my game just crashed with the message saying that texture is null (id:-1). It is totally fine when playing with no mods but once i swap to the mods version it happens.
Version: 1.20.2
Mods:
Wynntills and all performance mod from Artemis/launchy

________________________________

The game crashed whilst rendering block entity
Error: java.lang.NullPointerException: Cannot invoke "dev.tr7zw.skinlayers.api.Mesh.setPosition(float, float, float)" because "mesh" is null

 

Sorry, do not ask modded questions in wynncraft forums. If it is a wynntils issue, ask in wynntils discord. Also even if it was a wyncnraft issue, put it in bug reports, not questions

 

Does the issue persist without Wynntils?

 

No without wynntills is just stopped
