RailJack is gonna need some major polishing if DE is gonna add corpus liches, there's still tons of soft locks when the mission bugs out and you can continue the mission, forcing you to leave and lose all progress and rewards. This has been a bug for months now. There's even a bug where you screen will turn completely black and you can't see anything, and being unable to use blink while in archwings. I hope these are fixed because RailJack is not in a good state for such an expansion.
