Turn 175 and after clicking end turn the factions do their thing and move some guys around until it gets to Cyrene and nothing happens, If i load the End save file and repeat the process the same thing happens. This actually happened once before about 10-15 turns ago but reloading and running again worked.

In other bug discussions some people have said this is an animation repeating for an a.i unit or smt and thus never completing; so disabling the follow characters fix might have worked, the problem was that I can't see Cyrene at all unless i toggle the fow and that when I toggled the fow and looked [following the characters enabled] when it got to Cyrene it would just take the camera to a city and nothing would happen.

I had to destroy the faction with commands which is unfortunate but at least they weren't in my way or had any remote contact with me. This did solve the problem though.

Edit: Another 5-10 turns later and the problem has resurfaced, except this time it is the Free Peoples, so I guess my campaign is over which is a complete bummer and a bit of a big whooping deterrent for me since I doubt i'll ever want to play such a long game with the looming threat of a game ending bug over my head. Again though i'm positive this is a base game vanilla bug, but I don't know how to fix it.
