Just wanted to jump in to say that I am also having this issue in VW2023 with a file that was started in VW2023. Same issue - if more than one object is attached to a wall, they all graphically disconnect, while still saying in the OIP that they are "in wall". So if I have more than one door in a single wall, they "become disconnected" yet still say in the OIP that they are "Doors in Wall". This issue was not always present in this file, indeed it just cropped up into the file today!
