On FS2024, aircraft with 4 engines are having various inconsistencies with contrail effects.
I’m using the default Asobo contrail effects

This is the same template used in the stock MSFS2020 B747. The effects detach from the FX_NODE on each engine upon switching cameras.
Aircraft is at 26,000 ft, climbing to 30,000 ft (roughly where the contrail conditions begin). Flying from the exterior camera, I can clearly see when the contrails appear for the first time.
I go back to the cockpit view for a few seconds, and back to the exterior. Now all my contrails have detached from the engine and collapsed into the origin node of the aircraft.
I’ve tried using different nodenames, creating other nodes, etc. Nothing seems to work.
This does not occur on FS20.
