If you create a game, the computer AI will certain go after the creator most of the time. If you find this out, please submit a support ticket and let them know. As of now tho, I have stop playing this game until this problem has been resolved!
The computer has been coming at me like I slept with it's daughter. Always happens when a player drops out and is replaced by the computer/
Happens with me too!
I had even worse happen to me today: the AI awarded itself almost 40 armies when it wasn't even it's turn! I am positive of it, because Red was playing, Yellow turn next, then me. I was planning on taking down yellow when all at once two of Yellow's countries that only had a couple of armies each jumped up to 20 and 22. And not even on it's own turn!
There is one way to keep the AI from attacking you until the end. Create a board with only two players. Once the other player gets down to almost nothing, they will leave and the computer AI jumps in at the end. By this time, it's really too late.
