My friend and I are playing a multiplayer game. We're on turn 168 when I try moving a transport out of a starbase and the game will crash to desktop.  I tried moving a different transport and it still crashed to desktop.  Not sure what's going on, but never had this issue before.  Tried the Opt-in 1.01 patch and still the game is crashing when using those transports.  I have 3 transports that are all unusable as they will crash the game to desktop
