Weapon swap to crossbow via attack animation locks character

If you weapon swap from a non-crossbow weapon to a crossbow by using the crossbow's basic attack skill your character will hold the crossbow like a melee weapon and you will be unable to use any skill that requires the crossbow's animation.

Steps to reproduce

1) Equip crossbow (Set 1) and a non-crossbow weapon (Set 2)

2) Make sure crossbow basic attack is tied to the relevant weapon set (Set 1)

3) Switch to non-crossbow set (Set 2)

4) Try to use crossbow attack. (Bolts loaded or unloaded does not matter)

5) Your character should now be unable to use most attacks from either set. Movement and dodging is still possible.

It is possible to use a skill like grenades to break out of the animation lock, in which case everything functions normally. But this bug is making alternate weapon sets with crossbow mains nigh impossible.

In case it's relevant character is a Mercenary (Witchhunter)
