Sometimes when you have been in a long game and return to the menu, the game crashes too.
Also I think one of the desynch crashes is related to when a player is trying to use morph dragon, without having the necessary resources.
Sometimes when I use the minimap to fast-travel to a destination on the map, I end up at a completely different location (so far only when I wanted to go to the edge of the map).
On a side note, I think the light barriers indicating the area of the map is a bit too view blocking.
