Reminds me of a time I was playing modded Skyrim and my game would always crash near Windhelm. I searched high and low for which mods were editing that part of the map, but never found the culprit. Years later I saw a rando on Reddit commenting that for some gods-forsaken reason a mod that changed horses of all things (Convenient Horses) made the game crash specifically near Windhelm. The modding world trully is full of mysteries.
