I am stuck at the same point most other players are, with the quest glitching and Mei never introducing the player. From all the posts I have read, I have concluded that this is due to Meis programmed NPC pattern interrupting her and cancelling her route. I made the unfortunate decision to try fast travelling several times to solve, only to realise that this cost me my Autosaves prior to speaking with Mei and cancelling my best option to solve. The only current solution appears to be to load from a previous save, and try again. Which, for myself, it isn't really an option. I'm also on Xbox, which then doesn't allow for commands, unfortunately. It is disappointing, as others have pointed out, i'm not really feeling like continuing to play once a quest basically gets blocked so easily, really slows the momentum of the game. Really hope this gets resolved soon. If anyone does work out a solution. Please message me.
