Hi Matt,
I'm about to implement you amazing MGTileMenu on my App. I noticed that when the app is on the view controller that manages the TileMenu and no TileMenu is enabled, in this case if u leave the application and then reopen the application and u try to call a TileMenu nothing appears in the view but the Menu is normally active and u can touch it as it was a ghost! I saw this bug also in your Demo but in your case after a little touchin in the view you can see the closing animation and then the new TileMenu popping up!
Hope you ll give me some hint!
Thanks,
Riccardo Scambia
