I tried to take a screenshot of it, but screenshots don't capture cursors. Anyways, this is a very minor bug that occurs while you stand on one of the gates in Emberlight, and maybe other towns, but I haven't tried. While you stand on the gate, if you move your cursor above your head it still points downwards, but if you move your cursor high enough it will start pointing up and acting like normal.

I'm guess it has something to do with the zoomed in camera, because once you step off the gate the cursor will still act funky until the camera reverts to its normal angle.
