Hmm, thanks for the report. I'll see what I can do about this today.
Metro pass is still a problem. It disappears when a new area is entered, including going back one area. Absolutely amazing game otherwise though.
same thing happen to me today I I really don't want to play through it a 4th time since I reset my laptop and a save somehow got deleted
also I reset to my last save after I got the pass and I still didn't have with no way of reobtaining it
