dense forge
If I leave play mode after triggering any shape, all other shapes seem to get reset or something, causing the retractable block here to extend and then retract.
But the annoying part is what happens after. It's permanently destroying the gravestone on top of it from the editor, which stays destroyed even if I leave the dungeon and come back. Additionally, it seems to leave behind some kind of "ghost" gravestone, which plays its destruction animation every time I enter edit mode from play mode.
