Dalman walk up the main room to the first floor and found himself teleported to the area with the Last Stand strongbox. Couldn't get out as the door is locked.

Tell me you stole stuff. Please.

Was it lagging at any point, because that's what generally causes random teleportations in the few instances I've seen them.

Oh, and Dragonfire. Bad. No cookies for you.

Metro ported me out of the locked area, but that's about all there's to it: no lag, i just walked through the first transition stairs, and boom i ended up in the top floor (i guess, never been there before).

A little after that, (Angela) Listen in Silence was ported right to the other side of the map in the gate road area.
