it seems that the mob slaughter factory is crashing the server where i am playing when i place it in the overworld

Crashlog? Version?

mod version
industrialforegoing-1.12-1.3-58
it seems to be server sided since in single player it works
i will get u an crash report later this day

no crash-report is being generated, but here is the server-log just before it closes:

Edit: updated link

Sponge crash, it will be very low priority. It shouldn't have to stop the game for storing null in NBT.
