To clarify, I’m using MoveTo in Verse to move the PropMover, not the PropMover-specific functions.
I also have “Register with Structural Grid” and “Forcibly Structurally Supported” enabled on most of the props attached to the PropMover.
My guess is that there’s some kind of structural grid registration that happens when the game starts, but if a player joins in progress after the registration happens, they can’t build on the moved props.
Any ideas much appreciated!
