This bug can be observed with Rubick, due to him having no cast time on stolen spells.

Repro:
1. Steal Wild Axes as Rubick
2. Cast Wild Axes right behind you

Result: Rubick turns around to cast the spell. Once within the required angle, he casts it. But the axes do not fly towards the targeted point. They fly towards where Rubick was facing as the cast begun.

Expected: Wild Axes should fly towards where the spell was targeted, not towards where the caster is facing.
