Weapon-swapping causes game to crash if cast-on-minion-death is enabled

Playing Corpsewade pathfinder, i usually played windowed 1920x1200, dx12
(crashes also on Vulcan).

- cast-on-minion-death enabled on both weapon sets.
- when entering an instance or a random zone on the campaign map,
weapon-swapping near monsters crashes the game immediately.
- when disabling cast-on-minion-death, game does not crash
- when weapon-swapping not near minions, seems to not crash either
