Just checked it’s acting weird Also it’s “falling box” children length should be 1 not 2. I removed model from it and its length changed to 1.
I tried finding but couldn’t. ontriggerEnter is calling before setting position.
Looks like it is only an issue of the very first frame of when the scene is loaded. Cloning the falling block at any other time is fine (or enabling it later with a keypress). At a guess, the order of updates may be different when a scene is loaded compared to the standard update order.
