You're right. I over-exaggerated the problem, and wasn't really clear. What I really mean is it's easier to
accidentally exploit the AI. I never intentionally go out of my way to do it. I'm finding more and more things that break the AI without trying to actually do it in A17 than I did in A16. Though I'd admit some of it is just because it's still new so each one I find is fresh and different. But the quantity of them is far and away more than A16.
One most recent example out of probably 3 and half or so dozen just in the couple hours I've stumbled upon is dropping a frame in front of you in a doorway on a POI - if there is an existing clear path without a frame (like if they can go outside through another open door all the way around the house or even huge factory) the zombie will do that instead of coming to you - that wooden frame is just too much work for them

.... There's lots of little 'accidental' things I have just incurred while playing. It's so much easier to find them and so much more worse than before. I don't want to even notice or know of them but half the things I think to do seems to cause pathing problems. A lot of times I want to do something logical but I now know it will break the AI and be cheap so I don't even do it and risk death and do it the hard way. I have to anti-game the game.
