Yeah, found it out yesterday.

I've got problems with my computer wireless thing and also some other problems which all are probably going to get fixed today. So that means I'm gonna download GWX 2.0 tommorrow.
I hope GWX also improves exiting the game while at sea or underwater without having to go throught your office.. It's annoying and I found out that "Save and Exit" thing corrupts savegames somehow and makes your watchmen to be on bridge while the sub is submerged.

In other words stock game's saving and loading sucks so hard and every time I load the game I have to set those torpedos to F (fast speed) again. So long words short: Does GWX improve saving and loading and fixes this "savegames getting corrupt"?
