Solved: Packet crashing


JerryLy086

Recommended Posts

I'm porting some code (Create mod Shadow Steel tools, GitHub link below) from 1.14.4 to 1.16.5.

Link: https://github.com/Creators-of-Create/Create/tree/mc1.14/release/src/main/java/com/simibubi/create

And every time when I mine some blocks with the tools that toggle the event the game just crash.

Crash report:
