[sPVP BUG] Map Selection screen stuck and won't go away.

[Heiphz.5132]

A friend and me queued up to a ranked match, accepted it and when the Map Selection screen came up, we voted, the timer ran out and we weren't teleported to the arena. The window just remains there, not going away no matter what we do. We already tried:
- Changing maps
- Changing characters (The window still shows on the other character, lol)

- Entering WvW
-Logging into another account (It wont show in the other account, but when we return to the bugged, the window is still there)
-Repairing the game client

This window literally makes the game unplayable, its in the middle of our screens, we cant see anything and cant minimize it.
