Demon form - unable to cast spells while moving with weapon sets

Hello,

Currently, demon form is buggy if you have your skills bound to a specific weapon set. If you're in set 1 and you try to cast an ability that's only bound to set 2 while in demon form, you are unable to cast it as long as you're moving - you actually have to manually stop your character. I'm even using the weapon lock feature, so my weapon is actually in both weapon sets.

This makes utilizing the second weapon set tree for things like curses, exposure, etc. very painful to use, because not only you have to stop to first cast them, but then have to stop again to cast your usual spells to swap back to set 1.
