I get that as well at times. Always at 60% too haha. I know 2 mods that do cause it for me but load order usually fixed it. Not this time. I can start a new game and all is well, but I don't want to keep starting fresh every time. I can load some saves that have mods in them, but they are all just starting saves I created for future runs and all the mods are different as I keep getting more or removing ones I'm not a fan of.
