Hi,
Game: QP
Server: EU
Map: Lijang
Occasion: Observe a friend’s game
Type: Crash, game exited without warning or else
Situation:
I joined a qm game as an observer and was in map “Limbo” (where you see the map from below) - when it was to select a character at 0:28, I then pressed space (previous player) and the game instantly crashed. I restartet, rejoined and joined when ppl had then already selected charecters, I only pressed Mouse1 to get to the next player - not to trigger the crash again 
Possible cause:
- perhaps no one had selected a character and well trying to observe a then not existing player might have crashed the game.
