All I know is Tav jumped off the Nautiloid last night. First jump of the game, and she jumped off instead of landing on the other side. It was like she was trying to jump on the dragon's back.
Is it reproducible? Do you use mods?
I presume you already know that, but in case you don't, even if you "uninstall" mods "completely", sometimes they leave files in certain folders, and game starts to freak out because of that. If you are using mods, you are not testing the game, full stop.
