There's no problem with the fact that unhistorical things happen in the game. There is a problem however if a specific highly unhistorical thing happens every time. To use some examples from EU3: France being broken up into small states by 1700, Spain conquering all of North Africa, Catholic nations from central Europe colonizing Siberia. I wouldn't mind such events if they happened in a game sometime, but if they happen with regularity in every game I play then I think the balance of the game mechanics needs to be looked at.
Spain colonizing NA and England colonizing the Caribbean kind of falls under that category as far as I'm concerned if it indeed happens with the regularity that some posters here are indicating.
