I use the most recent version. Here's some specs:
After I login the freeze lag will start to occur. It doesn't always crash but it does hang for quite some time.
Ever since I've updated swapping between menus (Login screen, main menu, etc) causes my game to not respond and occasionally crash.
After I click the "Start New Game" button I get the screen saying that if you'd like to see the game completed to back it on kickstarter, then the game crashes.
