Tried removing any mods by her that I had and that wasn't the issue for me unfortunately... It's weird tho. While I was trying various things it randomly worked again on one save. I didn't change anything (was in the middle of testing if it was any of twistedmexi's mods), I hadn't left the game, still had a ton of other mods in, I just randomly went to see if I could go into build mode on a nordhaven lot and I could just fine. So I went to try live mode again and it worked! Then I couldn't replicate it again and I still can't... At this point I'm at a total loss. I'm not even sure if I believe it's truly a mod issue...
