quits server when picking up item

[KryptoLMS]

the mod quits the server when picking up items with the shulker in off-hand, and keeps quitting when i join the server until the item despawns

Hey there, thanks for the report. Can you provide the versions of both the mod loader and the mod, as well as the log of the server.

Is there any output or error message?

This is weird. I can't reproduce anything similar. What other mods are you using? Is there a specific setup where it crashes, or does it happen all the time?

[KryptoLMS]

quite a lot of other mods,

but it happens with just these too:

[KryptoLMS]

it happens all the time

[KryptoLMS]

do i need to have it installed on both server and client?

[1bacon]

This mod is fully server sided. Are these the server mods? There are a lot of client mods in there, only the server is relevant for this crash.

[KryptoLMS]

oh right, these are the server side mods
