1) Circumstances: It's late game and I'm rich. Whenever I complete an away mission, killing a pirate base or whatever, I have prisoners. I usually build a transport pod hub to get back to base quicker, and send the prisoners back one or two at a time.
2) The Bug: When prisoners land at my base, they are hostile instead of passive. They try to fight again. If I also happen to send one of my pawns back with a prisoner, my pawn instantly one-shots the prisoner when they land, because the prisoner is hostile.
3) What I expected to happen: they should still be prisoners. This is how it was in previous versions, and also it makes sense. I restrained them before launching them via pod, the restraints would still be in place when they arrived.
4) How to make this bug appear quickly: Start a game. Spawn a pirate base via console. Form a caravan with 1-2 of your starting pawns and dev console travel to the pirate base, leaving at least one pawn at your base. Dev console down/kill all the pirates. Capture some. Spawn some resources so you can build a pod launcher. Build it, fuel it up. Heal a pirate enough so he can be transported. Put him on the pod, launch him back to base. When he arrives, he will be hostile instead of captured.
Fixed, thanks for reporting! ;)
