Firstly I must apology for my poor english, it's not my native language.
Secondly I’ll try to report a bug / glitch as I’m used to Mantis in my job but in the other side ;-)

We were with my friends at the new North-Est airstrip between Krasnostav and Olsha, in the ATC Tower, looking for players and / or loot. Me and two of my friends had been killed in the ground floor in our back, whereas we had checked the whole building before.
One of my friends saw the shooter before he died, he was half in the ground and he was using a wall clipping near the not openable door at the ATC entrance. I came back to the site as a bambi and I took a print screen as you can see the file attachment.
Well I saw the same thing than my friend, and in fact there were three players doing this. But it's seems that when they left the building or going to the upper floor they loose their state.

Hope it help.
