I've played multiple games where it simply crashes (already reported and received a ticket).  My non-empirical observations seem to indicate a large number of crashes occur when ships form a fleet or merge/dock with starbases.  

My empirical observation is the debug.err file shows that the stack trace is generated after fleet formation.  

Debug Message: Fleet Created. [PlayerID 0] [FleetID 3108]
Debug Message: EjectShipFromStation
Debug Message: PlaceShipOnMap. tileX 56 tileY 152
Debug Message: Fleet Created. [PlayerID 2] [FleetID 3110]
Debug Message: CPlayerSystem::EndTurn m_currentTurnPlayerIndex = 0
Debug Message: CPlayerSystem::EndTurn m_currentTurnPlayerIndex = 0
Debug Message: CTurnSystem::RequestTurnState from: InNewTurnJob to: AwaitingNewTurnJobNotification on tick 56819
Debug Message: Dumping Stack Trace:.,..

Has anyone else observed this behavior?
