Xaku's Grasp of Lohk not disappearing

[gugugugagaga]

The weapons from Grasp of Lohk sometimes keep floating around, even when the ability is not active anymore. Casting it again, doesn't fix it, it just generates new weapons which do disappear, but the previous ones remain. It's a bit distracting as it blocks a considerable amount of my view as they aren't 'stuck' to the frame's side as when they are cast and move around the screen.
