New bug or ?

Hello guys, i never saw shit like this before and that's the reason of my posting..

I runed and ducked before the ladder and then push out ctrl, but i didn't stand up ! It's not my keybord buttons problem, cause i made it with +duck on wheelup on 3 or 4 try.

Update:

I don't think he could make a screenshot of something like that :/

downloading demo ;)

it's not new... it happens if you double-duck or duck and stop ducking fast in a place where you hit your head... then you keep ducking, unless you press duck and wait a little time before stop ducking

lol this is from some months just press jump and duck and it will be ok :D
