Diplomacy bug

[Moroccan_Andalusi 2]

Hi,

I was playing a Karaman>Rum campaign and managed to form Rum.

After a few times of playing whenever I load up my Rum game whenever I click on 'Diplomacy' it won't show any relations. I tried loading other games and every game has this problem. Whenever I try to look at diplomacy through "map modes" the screen turns black and the only thing I see is the flag of my country.

I even started a new game and it still did not work. Can I fix this? This is a serious issue that needs to be fixed ASAP.
