Hellfire seems borked

Update, I have a brand new shiny bug to report that came with the last time it stroked out on me.

I was unable to run forward at all. I’ve never encountered that in almost 12 years of playing. I literally had to backpeddle about 50 yards to turn in a quest. Couldn’t turn at all, with keyboard or mouse, only walk backwards and strafe.

Is someone pranking me? Because these bugs seem almost deliberately annoying. lol
