In the early access they already have a ship crashes and game over message. I cleared out the transponder room and tried to go back into the nautiloid, then I got a message that the ship crashed and everyone died.
Happened to me once too and I hadn't saved in a while.
I would be ok with the 15 round penality, after all the game tries to make it urgent to reach the transponder. Doesn't make sense, that you then have all the time in the world to clear the room.
