I'm playing with the 1.1.5 version of the mod in my multiplayer server with my friends and when we get close to a tremorsaurus or get attacked by it we instantly crash out.

crash log
latest.log

also my citadel version is 2.6.0

at net.minecraft.client.model.PlayerModel.handler$bad000$entity_model_features$emf$RenderCustomModelOnly(PlayerModel.java:560) ~[client-1.20.1-20230612.114412-srg.jar%23358!/:?]

issue is with entity_model_features

Thanks
