i tested it 2 times , 1 time with a new AE2 version and other outputs came through.

Crash Report 1
latest.log 1

Crash Report 2
latest.log 2

I could not connect to the server anymore.

After disabling OWO Lib & Things Mod i can connect and no crash report comes

Have you checked if it's actually owo-lib and not just Things?

wisp-forest/things#41

This crash is almost certainly caused by Things and not owo, as such I'll go ahead and close this issue
Cheers

@SpigotDE It certainly comes from Things.
This version should fix the issue: https://github.com/Bob74/things-1.18.2-fix

You need both:

• things-0.2.19+1.18.jar
• owo-lib-0.7.3+1.18.jar
