(edit: i added a video, but i cant see it here, no clue if it made it to your side)

hello, i am not sure how to report this as it BARELY leaves behind a log file when it happens, but my game seems to lock up after respawning due to
[18:39:00] [Thread-18/ERROR] [ne.mi.ev.EventBus/EVENTBUS]: Exception caught during firing event: Cannot invoke "String.replace(char, char)" because "s" is null

MC Version: 1.20.1
forge version: 47.4.0
EMI version: 1.1.22 & 1.1.20
JEI version: 15.20.0.106
Tinker's Construct Version: 3.9.2.37

this is being caused, i believe, by something called a "modifier_crystal" from the mod tinker's construct, i believe this is the issue from looking at the logs

below is the snippet from just before the crash.

i can't see to get a log from after the crash as the game locks up completely, and then i have to force exit the process from task manager.

this occurs EVERY time i die, and click respawn while playing on my server, but not in Single player...

EMI is reloading in this log, and is unable to lock up your game. Without a proper log it's hard to say what it is, but something else is going on, sorry I can't help figure out what

debug.log
latest.log

i used a different launcher that didnt flat out crash on exit.

the problem is still there, BUT I GOT A LOG NOW ^.^

hope this can help
