Members of my building community keep telling me that people are exploiting by rotating the public bases sideways. I looked into it and found out that if you place an unanchored part with a hinge onto the base (with the hinge connected to the base) and then try to resize it (while it is still unanchored, studio anchors parts when you resize them) then the part will disappear and the entire baseplate will rotate. I don’t know if this is new or not, I got around it by automatically anchoring parts when you edit their dimensions, but it seems important. It started happening with cars, too, where if you resize the seat on the car, the entire object flies away. I presume it was a new update to how surface connectors work.
The same thing happens to me.
