I encountered this bug, after calling in the Ambulance to pull out my snyf from the bunker-caverns in the Maedecan Desert. After I spawned back Pirizuka couldn't move, and if I switched into first person, she started lungung around the whole place, glitching. I will try to take a screenshot if it happens again.
I've had this happen once too, seems it is somewhat hard to replicate on command for a screenshot, most of the times hitting "i" a couple times helps, or sometimes at least when being unable to move for whatever reason. Will try to get screenie or footage now as well.
Okay, so after walking around a bit, Man it is really hard with physics piri to walk through these tight hallways/tunnels. Man. Ps, 'not being able to move' bug found yet
