Random Event slow-down in late game

[Jrandom]

All friendly Dom. Just some recently former Indy provinces without good Dom.

I started another game as LA Ernor, this time with 16 other AI. Just got to my first level 8 tech, so solidly mid-game. I have positive Dom in my lands, the random events have slowed down again. About 1 every other turn. In the beginning of the game it was about 3 random events every turn. Over-all the Dom is better in my provinces now then in the early game, but I get less events.
