Exception in server tick loop

[lacomarca]

Hi,

I got this crash on my server and appartently is due to your library and we weren't using any of your mods related yet. Could you please take a look and let me know? We have thutcore:8.0.1 and thuttech-1.16.4-9.0.2 in forge 35.1.4 and Minecraft version 1.16.4. Find attached our crash report. Could you please help us with that? thanks in advance!

try updating thutcore and thuttech and see if it is fixed in thutcore 8.1.1 and thuttech 9.1.0?
