I am using Mohist server, MC 1.19.2 (Forge 43.1.3 client). Occasionally, I get kicked off of the server due to an error, and I can't get back on. Here is the gist with the error. I also see other people having the same issue.

Just for clarification, the filename is minecraft-comes-alive-7.3.21-rc.2+1.19.2-universal.jar, and I'm not sure how to reproduce it or what causes the issue in the first place.

Still can't reproduce but a lot of things changed, maybe its fixed now.
