I was running with a group, screen went white and avatar appeared to go prone at the same time. I thought it might have been my graphics card, but when I logged back in after a full reboot of my machine, my avatar was stuck in tree.

Tried vaulting, hopping servers, dropping items from my inventory (caused crash first time I did that.), going prone and rolling, auto running and sprinting, mashing keys randomly. Calling out for someone to kill me.

I do not appear to be loosing hydration or energized as quickly as I would unstuck, especially considering I sprinted in place for at least an hour straight.
