I am playing as Nakalim with Endless difficulty settings and the Long time setting. On turn 61 I passed turn and the game gets stuck in ending turn, It will end up generating events for the next turn but will never exit the old turn.

The Exception thrown in the log files is : 

Default     The given key was not present in the dictionary.

 at get_Item in :line 0 

 at ServerPickPVEOutcomeForOperation in :line 0 

 at ServerPickPVEOutcomesIFN in :line 0 

 at ServerBeginTurn in :line 0 at MoveNext in :line 0 

 at Run in :line 0

This happens in the same time cycle as the events related to : Academy ship buyout search. 

and immediately after the gameplay event for : [Academy] Colonization Period Formula = 15, On Turn 61, Last Colonization Turn: 36 

I am getting an error when i try to upload the logs of the save to this forum. so hopefully this is enough info. If you have any questions for clarification please let me know. 

I tried to circumvent the error by disabling the academy, but sadly this leads to another exception:

04:46:37:015 Default STACK Argument cannot be null. Parameter name: empireWithWhichTheStatusChange
