This is an adaptive skin drawn from Zspheres. The problem is, using both the move brush and the deformation options in the tool panel, the tail pictured above will only move in the up/down y-axis. The problem originated before I drew the adaptive skin, when it was just z-spheres.
I assume I just accidentally clicked some option that I am unaware or something like that, but maybe this could be a bug too. Any advice is greatly appreciated
