Multiple Duplicants Teleported to Different Planetoid Upon Relaunch

I had recently flown my first duplicant to the marshy asteroid, After a few cycles I saved and quit, I came back and upon launching the world, 5 out of the 9 duplicants from the starting "terra" asteroid are also now on the marshy asteroid without me doing anything to get them there. Launching the autosave from the start of the cycle fixes this issue, but if I save and quit and load from my most recent save instead of the autosave, the same bug occurs. It is always the same 5 duplicants (The ones named Pilot, Cook, Farmer, Ruby, and Shawn) that get teleported as well, and they get teleported to the same location on the asteroid.
