Not reproducable, the crash hints at a concurrent modification exception occuring somewhere in the update method of entities, hwoever, that happens in MC classes, not cqr classes and we do not modify these. Report it to engender, we can't reproduce it, the last call in CQR code is a call to minecraft base classes

[rebarakuk]

This might be a tick error, because when I installed tickrate changer which synchronizes server and client ticks, this crash doesn't happen

[DerToaster98]

Again: This doesn't happen with just CQR, report it to engender, we won't work on this and it is not reproducible for us, the crash report is also pretty useless cause the exception can't raise from where it last was in our classes.
