Not sure if this is a bug or not. Either way I've mentioned it in general discussion and some people suggested I should post it here.

After patch 1.20 you made it avaiable for character to stand up while using hotkeys set for moving. However WSAD keys make you stand up no matter what you're using them for. I personally use them to rotate camera. In a result whenever I'm sitting and try to rotate my camera my character stands up. This is not my issue only, I've heard from a few other players that they're having this issue as well. I hope that wasn't intendend and that's actually a bug that can be fixed.
