This bug existed since beta,it was reported several times, but was never fixed. In particular I will try to explain what happens. I play Templar who uses staves so I don't know about other classes but I think it's probably true for everyone. So sometimes when I ride my horsie and enemy NPCs hit me and drop me to the ground that strange "stun" occurs. I play First Person view so once I get dropped I see my hands in that kind of "scared" position. And after that I can't do anything at all. No matter what skill buttons I press or if I go to inventory, first person view is just stuck. And it really sucks as these enemies still beat me at that time. If I switch to 3rd person view, I can fight back and do everything, but once I switch back to 1st person view, I see those hands again and it's stuck. The only thing that fixes it is log out. Even alt+tabbing the game doesn't fix it btw. And I repeat, this bug was in beta and it still exists and it's actually annoying. I attach couple of screenshots of those "hands" as they are stuck and a screenshot made in 3rd person so you could see that the character is standing normally. Please share if you encounter this as well and let Zenimax know about this issue.
