Dropships go limp after being active for too long

[Architector4]

Describe the bug If a dropship stays around for too long, it suddenly stops being able to accelerate and just falls down, even though the big thrusters appear active.

To Reproduce Steps to reproduce the behavior:

1. Summon a dropship, either a standard one or a dummy dropship.
2. Wait for a while. I'd estimate about 20 minutes or something.
3. Observe it go limp and just fall down.

Expected behavior I expect that to either never happen, or be followed with a slowly depleting fuel bar and the big thrusters visibly shutting down and making no more sound.
