don't want to kick off the old "you score i score" argument, but there is definitely something at work there sometimes, at least from level 3 up. it's impossible to prove, but it just feels scripted.
to be fair, it also happens the other way around. once the CPU goes up by one it starts to play really shoddy, at least for the next minutes, allowing you to catch up in the score, so to say.
maybe you also noticed that once a party has equalized, the next 100%er of that party will most likely hit the post or the cross bar or blow a fool proof opportunity. i was once up 1-0, and a shot bounced of the CPUs keeper to drop on the head of my diving Castello who was like 4 steps out from the goal line, open goal, no defender, no way to miss that one. i held the LAS to the left (goal was on the left side of the pitch), yet the ball hit the far (right) post and bounced off. i am not saying it's not likely for that to happen, but it just felt so much like a higher power meddling there.
