I found incompatibility between fabric immersive armors 1.3.3 and 4 and so I heard you talking crap about minecraft combat i difficulty. Crash file does not appear, only information about exit code 1. I hope it is possible to fix that

Without error I can't fix it. Double check the latest.txt and debug.txt files.

Ok, I found crash report in logs: https://pastebin.com/EW8X7bk6

Awesome, thanks!
