I downloaded your save game and I have no issues with Dakota. I can travel, no wings on any outfits
When you tested vanilla, did you upload her to the gallery and put in a new save ?
I'll try that, but the Wings don't appear until she changes her outfit. That's why she was in her formal outfit in that save, I was going between her Everyday and Formal Outfits to test it.
Did you have the loading issues only when she had the wings ? I still can't duplicate
I should have paid more attention to confirm, but I'm pretty sure it WAS when she had the "invisible wings". I'll test a new vanilla save with her in a sec, but honestly if it comes DOWN to it, it isn't literally game-breaking since I don't usually play her Household, but I figure I'm not the only one having this issue. She's part of a 17-Generation Legacy so restarting or deleting her are off the table lol
It works all totally fine for me though so she can't be that broken.
I just loaded your save and it worked.
Did you try renaming your user folder and just copying over your save ?
