This isn't a major and it is easily solved by doing a simple a relog, though some people might go and exploit this, so I chose to report it.
I haven't tried to recreate it yet because... I didn't want to go and kill myself.
My character died, well she went into negative, after I got healed and got back on my feet, even though it was a bit glichy I was able to run normally if I used my mouse to move around even though I was heavily overweight, I relog and it was afterward.
Could probably try and see if we can recreated this with the help of a DM or if someone as a cleric to heal the "victim" could try it as well.
