I got this error while hosting a server using this mod. I'm not sure what caused it but the issue seems to be from this mod.
Error found in Server log:
`[13:43:24] [Server thread/ERROR] [ne.mi.ev.EventBus/EVENTBUS]: Exception caught during firing event: class net.minecraft.world.item.AirItem cannot be cast to class com.majruszsdifficulty.items.BandageItem (net.minecraft.world.item.AirItem is in module [email protected] of loader 'TRANSFORMER' @7ed49a7f; com.majruszsdifficulty.items.BandageItem is in module [email protected] of loader 'TRANSFORMER' @7ed49a7f)
