After installing patch 0.9i when channelling disintegrate with my sorcerer and pivoting the character around by moving the mouse, the disintegrate animation stays in place, i.e. it stays oriented the way it was when channelling started. The character itself does rotate and enemies that it is facing after rotating are receiving damage from disintegrate in the normal way, so it seems it is only the animation itself that does not move but in every other respect the spell is considered as being aimed in a different direction.
I don’t have this issue but after installing 0.9i my disintegrate is completely invisible but it still damages enemies and moves around.
