Mod to fix duplicate pawns

[tsmt1001]

I've noticed quite a few times that Rimworld generates duplicate pawns, but this has been especially bad on my last couple of games. I have seen it on vanilla and on modded runs. What's especially bad is that when a duplicate pawn is generated, and it is in a relationship with a colonist, the duplicate (who is off map and in some other faction) becomes the colonist's  spouse and the one that's on map turns into a stranger. Is there a mod which fixes duplicate pawns? Ideally it should delete the one that's off map and restore the relationship. Otherwise every time I load the game, I have to go into dev mode and manually fix the relationships.
