Nothing comes up for me when i enter arena or ready check. Manually clicking minimap button doesnt work either. I dont use any add-ons that interact with the talent UI so im not sure where the conflict is. No LUA errors either

Hey, it's weird, I haven't encountered this issue yet. Are you sure no LUA errors occurs ? (you can catch via BugGrabber/Bugsack). I'll probably cleanup the code a bit anyway for pre-patch, hope I'll spot something...
