This only happened once in over several hours, but I was playing Conquest on Siege of Cairo when it occurred. I got taken down by an enemy infantryman. When I pressed space bar to let my character bleed out (settings set to toggle, not hold btw) the progression bar for bleeding out suddenly completed itself at the same instant that I was engaging the bleed out function, and then I was permanently stuck in a downed state with no way out. I could also hear the constant buzzing at the high pitch you would hear at the completion stage of bleeding out. Since I don't have access to "redeploy" in the menu from this downed state, my only way out was to leave the match. I did wait for one medic, but he ran right over me as if he could not see any option to resurrect me. It's very unclear to me what causd this to happen, but it's a pretty bad bug when I'm forced to quit my match.
This happen to me too just about now, but i was able to be ressed by a support. The only thing i did differently was in the middle of skipping by holding space was also interrupting that with checking the scoreboard unsure if that is what caused the issue or not. Got that part recorded but not when i got ressed: https://www.youtube.com/watch?v=vJhL-jXFaoQ
