I'm not sure if this is a cursed save file but I have twice now captured a star liner and despite the game telling me that my shock troops teleported back to my ship with captives and manually doing a personnel transfer to teleport passengers to my ship I have not been able to take captives. I have attached a screen shot with the report log below showing the game telling me my troops took 225 captives then me immediately going to security where it says I have zero captives.

In previous missions this worked fine, I think this may have started when I tried to capture a destroyer. I launched a full salvo at an enemy destroyer knocking down its shield and disabling its engine. I then boosted 0.9 towards it to get in boarding range. After a brutal boarding action I took the ship and I got the normal prompt telling me about casualties but when I should have gotten the prompt asking me if I want to leave guards on the ship and then the report of my shock troops beaming back with captives my ship moved forward which caused the nav computer to alter the course. I then went into the personnel transfer menu and saw that there was nobody onboard the destroyer! I was near a starbase so I could get those shock troops back but I was thinking that may have been the start of the issue. I have attached two screen shots below showing the report about the successful boarding and nav computer movement and then the next one with the scanner showing nobody on board.

Edit: I restarted the mission and upon finding a starliner and forcing it to surrender I'm still getting the bug where despite it saying that my troops have brought captives over my ship doesn't have any on them.

Edit: I verified the game through gog galaxy's launcher and restarted the mission again. I ran into a starliner which I disabled and successfully demanded surrender and boarded. My shock troops came back with captives, I then went into the security tab which showed I had captives, I switched to torture and sent over a prize crew to the starliner. After the star liner was on it's way back to a starfort I checked security tab again and my ship read 0 captives. I am on the first mission of the centurion rank if that helps.

Edit: I can upload save files if need be.
