Its because the game you load is never exactly the same game that you saved.

if you look closely you will find far more little changes than just diplomacy.

The worst thing that ever happened to me because of a reload.... the Drengin were attacking me with mighty fleets - some other moron went to war with them and all their fleets turned and started off in that direction, i was relieved.... saved the game, reloaded, upon reloading all those fleets immediately turned back around to come to me!

So nowadays, if i am at a critical point in my game, i prefer to leave my computer running overnight rather than run the risk of things changing with a reload.

I dunno? My guess is that it is because everything in the game occurs in a particular order, and the order of events as the game progresses is one factor that influences the AI to do what it is doing. When you save and reload, the AI is simply given a pile of stats to assess, the order of events is gone.

This is what i mean.... in my earlier example, the Drengin ships turned away from my area to attack someone else. Its because the order of events was that the declaration of war with that other AI occured at that time after already being at war with me for some time. The order of events influenced the Drengin AI to decide to send its fleets after that other AI.

Then when reloading the game, that order of events influence is lost, the AI is given the raw data of who it is at war with and it reassesses who it wants to focus its attack on.

That's my theory anyway, now idea if true?

In the OP's case, when reloading, the AI is also forced to assess from raw data if it needs to send any diplomatic messages.
