So I downloaded the 161 version of dark utilites did not fix the ChatFormatting crash from a previous issue. I am still getting it

Huh, this is very weird. I specifically tested the code on my own server to make sure it was fixed, and didn't run into the issue. However the crash log does make sense. I am wondering if Mojang secretly pushed a new version of their realms library and we don't have the same one. Either way I will attempt to fix this issue again. Sorry for the trouble.

Okay, this issue should be fixed now. Please let me know if it's still not working.

This issue has been fixed
