It's the FontRenderer bug

[Vladg24YT]

Tried another client, the issue is still present. Will try Smaed's jars next

java.lang.StringIndexOutOfBoundsException: String index out of range: 8

Ok, I'm dumb, it was the Smaed's jar. Idk if it is fixable server-side though.

[Vladg24YT]

Closed as it's a client-side issue
