Hello, I'm developing a mod and want to make it schematic-proof, but I noticed the function OnPlacementBySchematic was not called when I do a undo then redo with the schematic tool in game. It's called as expected when I do a copy then paste, but not after the redo. As I'm trying to copy/paste block entities which are linked to others, it becomes hard to know when to compute a delta and move the connections. Any ideas ?
