I'm playing Chapter V: From the Grave (KotFE), right now. The Gravestone is already populated. I am seeing many Alliance members performing menial tasks; and Koth's crew is already there, with him in engineering.
This makes absolutely no sense. We just escaped the swamp. The only people who should be on board are the PC, Lana, Senya, Koth, HK-55, and a few refugees that we found in the swamp. We haven't even made it to Asylum yet. So Koth's crew should definitely not be present yet.
