If i send this particular propeller into space then back into atmosphere it seems to "forget" its back in atmosphere and does not produce thrust again. Haven't tried any other propellers yet. I've tried 2 different atmospheres JUNO/SEGERRA and no dice. I can get the propellers to work if spawn on JUNO but once they leave the atmosphere and come back no thrust is present at any RPM. Could this be due to them being slightly damaged? None are fully destroyed during this process but theres almost always a bit of damage. The attached picture is after leave JUNO atmo and returning. Even if im going too fast and turn them on (or increase blade pitch) i'd expect to see some kind of difference especially when they are at a normal blade pitch angles of regular blades.
Happy Bug Hunting
Edit #2: It have nothing to do with quick saves. It seems as though i can leave atmosphere and come back. However i cannot reach a stationary orbit and come back and use the propellers in atmosphere.
