Door locked or otherwise unusable for Visitors in Gallery house?

Hey @catloverplayer. I do use MCCC only. It definately seems to have been related to the Welcome Wagon, because when I updated MCCC and repaired the game, the four neighbours were still standing on the deck, they dispersed and then a more ‘normal’ welcome wagon sort of ensued.
I will update if it really turns out their friends can’t get it, but the door seems okay now. One of the delayed welcome wagon came in at least (the others got upset and went away pretty quickly).
