For some reason with optifine installed, the realmsclient classes are missing, not sure why that would be. Sounds like an issue on its own.

That said I used the wrong class, and switched to the TextFormatting class instead which is what is normally used, which will probobly resolve the issue.

But to be frank, this crash isn't FCB's fault.
