Cast on Shock, Weapon Swap and Weapon passive tree points don't work and cause crash.

Tried to set up a Cast on Shock Comet setup with Weapon swap for the comet. If i set Comet to use weapon set 2 it won't let me activate Cast on Shock buff whilst weapon 1 is equipped saying not enough spirit even though I have full spirit. After checking/unchecking the "Used with weapon set:" boxes the game crashed.

It super bugged for me too. No crash but I can't get it to work now it says Missing Socketed skill.

Its so bugged.
