This is an error that appears at random points in my server and I haven't found the exact cause yet. The full error is as follows:

This was tested on 1.19.3
Are you able to narrow down what specifically you were doing before this error occurred?
It's only been noticed in the console after the fact and only when other users were online, not when I was online unfortunately.
I've got a suspicion the error is caused when crafting and shift clicking to craft in a custom stack. I'll try this later and send over any results
I have also experienced this issue. It started happening almost immediately after adding this plugin to my server. The culprit turned out to be one of my players stacking 64 totems in their inventory:
EDIT: They then did the same thing with a saddle, which had the same effect. What gives?
we also have this issue on our server and dont use any Traps to stack.. we also dont know at the moment what causes this...
