Question; Gallery considers a lot modded that has no mods/cc

N0NoTToN0N

Wondering if anyone can help with this. I built a lot where I used CC and wanted to upload a CC free version so I took all the CC out (I'm pretty sure I didn't miss anything) and redecorated. It's still considered "modded" when I save it or try to upload it to the gallery. I've moved it, deleted my library saves with internet off and can't get it designated as un-modded. Don't ask me why I didn't do the vanilla version first. Doh!
