First of all I don't know if I'm posting this in the correct place but this is what happened to me. I was playing in my regular character and everything was fine, logged out and about 30 mins after I log back in. Everything seems to be fine but the weirdest thing happened. When I went to drink a soda my character just starts to crouch and laying on the floor, rolling and so on until he ends the drink. I thought it was weird since it never happened to me, but the thing is, after that I can't vault anymore! can't jump through fences and so on. Here is where it gets even more weird, I joined my friend in an hardcore server (which I never play) and the problem seems to percist. Can't vault in hardcore too. So I met a few fresh spawns in the town and they asked me if I broke my legs (everybody seems to see me as I got broken legs) but I don't of course. While speaking with those guys, everybody seemed to be bugged and one of the guys had the same problem as me, 2 guys had invisible weapons and were able to melee with it and kill zombies and after a while one of those guys wasn't even able to move. I never heard about this issue and now I can't vault in any of my characters (both regular and hardcore) and I've suicide 3 times so far and it doesn't fix, the only thing that happens when I get a new character is that the first 3-4 times I press V my character crouch but after that it does absolutely nothing. PS: I've searched about this issues on the forum and on google and I wasn't able to find it, so I'm sorry if this is a repost. I'll also update this post if I get news about the subject.
