I haven't tested it yet with other buildings or circumstances and not sure about its influences, but here's what happened:

I had one weapon on my back, took another primary weapon in my hands and entered police station in Gorka. In first floor there's s single room with a bed (http://i.imgur.com/es5aptI.jpg), so I stood in that corner where I am pointing, between the wall and the bed and accidentally my legs got stuck into the floor and I could not move. Half of my body just stuck into the building. I then had to run and press vault to escape.

I don't know if holding two primary weapons had any effect, probably not, just re-told how it happened.

Tried again, but this time, as soon as I glitched in I went prone and into first person mode, and this happened: http://i.imgur.com/XkqOKTP.jpg

Of course I could freely move while prone around all police station and see everything perfectly.

I know there are/were similar glitches in Airfield hangars, but not sure if they are fixed as I never go there anyway.
