mate, it's a bug, it's only arenfield, nothing else just that town all else runs smooth, and believe me my pc can handle a game like this easily, I don't attack the dev this is not that i love this game and the dev too, to tell you 2 updates ago i had the same problem, managed to find a solution to it, and to tell you an event was BUGGED, but this time i can't find the problem, and as it's not the first time an event bugs i asked if there really is no fix for this
and btw i shared a full ntr save here which took 80 hour, so believe me i like this game but i can't play it if it's bugged and arenfield runs on 2 fps
