chaining Kelari abilities targets random locations (if not moving mouse)

playing click to move (not sure if same on wasd)

if i hover my mouse at range and do kelaris deception, followed by kelaris brutality (without having moved the cursor) then brutality is fired at a random direction away from kelari himself.

if i move my cursor slightly between the two abilities it fires at the correct target location.

reproduce bugged behavior: move your cursor somewhere, cast deception, cast brutality without moving cursor.
reproduce intended behavior: move your cursor somewhere, cast deception, move mouse one pixel, cast brutality.

edit: sometimes still seems to happen even when moving cursor but cant figure out why
edit2: ... ok keeps happening alot still so idk :(
