When 2.3.11 already installed:

Was this ephemeral or did this keep happening? Also where did you get MI 2.3.11 from? CurseForge?

Yes, curseforge. I just turned on option in config and now got a different message:

Which version are you on? It's normal that it suggests 2.3.13 if you are on an older version.

Just updated to 2.3.13 and to Neoforge 21.1.209
And got crash on launch:

Yeah see #1181 😄

I have a latest tesseract-api-neoforge-1.9.0-1.21.1.jar
Probably, I need not update, but downgrade :)

Now with the new version of tesseract api the issue is fixed

Is the original issue still happening? May have been a hiccup in the CurseForge API?

MI's version comparison logic is not great and could be improved, it's just very difficult to test this. 😉
