Save&Exit causes a softlock freeze (sometimes, Multiplayer)
Game will freeze on Save&Exit when leaving a multiplayer match where you host, sometimes.
Also, if another player is loading anything while you (the host) is saving, the Host will be stuck in a lagged Save-lock, where the game thinks it's saving, forever, and the game runs at ~75% speed.
Kind of annoying when saving, the one safety fallback of the game, is bugged. >_>
