However, there is still one case that isn't fixed, were if you quick cast the ability right on top of your character's position the ability might not fire at the correct location. We know that this sucks, but we decided to go with a partial fix that addresses most of the issues, while we're working on getting a full fix with 4.19. Sorry for the inconvenience and thank you for your understanding.
