Bug/Issue Multiplied crewmates [SOLVED SOMEHOW]

Hello there, I have a problem.
Due to player file corruption, I had to use the earlier backup file, but, unfortunately, the file saved progress on death of two my crewmates, respawning them. However, I've already had the same alive crewmates on the ship, so there's four of them now.
How to fix this?

 

I dismissed one of the crewmates.The original has left the ship and the clone is still there. Probably the error is in the ship file.

 

I wrote in SB Discord support, and somehow solved it.
Now I have a weird way to solve this issue, but it may not work for you.

1) Dismiss the cloned crewmate. The original should leave the ship, and the clone should stay and work as a crewmate.
2) Take the clone with you on any planet.
3) Turn on admin mod by writing /admin in the chat
4) Use /entityeval mcontroller.translate({0,-666}) on the crewmate clone (keep your cursor on their sprite). It kicks the NPC into the void.
5)Turn off admin mod by writing /admin again.
6) Return to the ship. Sometime later the clone should return.
7) Restart the game, and crewmate should return to your crew.

P.S. Thank you, [Betabound Mod] Silvia Sokolova, for help
