Hello! Hoping someone can help with a very peculiar problem.
I'm getting my app up to the current version of NGUI but as I move our way up, I'm encountering a very strange (and seasonally appropriate) ghost panel bug when I upgrade from 2.2.4 to 2.7.
Everything worked before, but somehow on every scene, including new empty ones, there is a ghost panel on top of everything else.

Where would this be coming from? How can I make it go away to continue upgrading to NGUI 3.x?
