I did some additional testing after you said level opening might effect things.
Saving, Quitting the game, Starting it back up, Leaving the Menu world and then Loading everything makes objects drop to the ground.
Saving, and then Loading works perfectly. Like a quick save/load
The only difference code wise would be opening the world. The saving and loading code is exactly the same.
I’ll see if i can recreate it in a blank project and then link it.
