this is probably not the best place for a bug report, but i got stuck on the alien ship... i took a character there, and when i went to interact with the character in the specific room, the character just vanished.
After reloading, i can't even get into the room any more, but i am also not allowed to return to my own ship. no way to progress.
But from what i'm seeing here i have pretty much finished the game anyway so i guess its no big deal. maybe in a few patches i'll load an older save and get back to where i was.
