Sometimes when you get cut on barbwire it continiously cuts you untill you log out or crash your game on purpose.
I tried crawling out of my base before I made the inner wall a gate. So I crawled over a barbwire that was just laying on the floor(not mounted yet) and got 7 cuts, but I couldn't bandage myself. I heard on the character that if possible he would have had way more than 7 cuts because he was rapidly making the grunting noice off getting cuts untill I closed the game application. When I logged back in he was quiet and I could be bandaged again.
The first time this happened I just walked into a mounted barbwire one time when unlocking the outer gate. my squad were all there and we all bandaged together after I closed the application. Would defiantly have died on my own when I wasn't prepared.
The second time this happened I was unmounting a barbwire mounted on the upper side of a fence while standing on top of the wall. Walked too close and the same thing happened. 7 cuts and more where happening but not adding on after the 7th.
Quickly closed my application so I would stop getting cut and bandaged my self 7 times. Blood was on empty after I finished.
The 3rd time this happened was when I crawled under the fence and got cut on unmounted(!) barbwire laying on the grass.

2 of my squad mates have had the same bug happen while walking into a car-tent. The character is trying to run through a invisible wall covering the opening(also a frequent bug) gets teleported inside to the back wall of the tent. Walks around and just starts to bleed out of nowhere. 7 cuts and more rapidly happening. They also need to somehow log out and log back in to be bandaged.
