[Genhis][2.0.43] Asteroid collectors causing high memory usage

[DemonicLaxatives]

* While testing stuff in the editor, I built a lot of asteroid collectors and sent them towards the shattered planet.
* At some point the game started using an unreasonable amount of ram.
* The game would then always use a lot of memory while the save was open, about 10GB, pretty much all of the spare memory on my system.
* This was resolved by deleting the collectors and undoing it.
* I tested the save on 2.0.47. and the behavior persisted.
* I am however unable to produce the exact steps to arrive at this state, but I've provided the save in the attachments.
* In the attached save there is the platform "grapper", that is where the problematic asteroid collectors are.

Thanks for the report, this is fixed for 2.0.48. Asteroid collectors disabled by circuit network are still tracking asteroid chunks, so that they can immediately start collecting when re-enabled, and in this state they didn't do their cleanup operation causing "nullptr" entries to pile up.
