I'm getting a variant of this with WoT 1.9.0.0 and Aslain v1.9.0.0 #03 .  Sometimes on returning to the garage after a battle the game just hangs.  I end up having to click 'Close Program' on the popup after clicking in the game.  Windows spinning circle 'busy' indicator is there, but sounds are playing, including the end of battle music and the garage bord song. Obviously the first thing WG support would tell me to do is Safe Mode, so thought I'd report here in case any other Aslain users
