Spore Sack causing server crashes when player dies (NeoForge 1.21.1)

[gamerpotion]

Hi, we have had reports that when players die with the spore sack in their inventory it crashes the whole server. When putting the spore sack item in storage and dying it did not crash server. Using relics-1.21-0.9.0.1.jar on NeoForge 21.1.54 server (modpack: Vagrant Saga)
