it was on the desktop version where I'm having this issue.
Just tried again and it's doing the same thing. when I put the cursor on the flair button, you can't click it and it says not available for this community..
35+ characters (each character having versions SS1-SS6 that you can select by using start+a/b/c/x/y/z buttons)
80+ stages
OpenGL enabled
