Witch-potion

( samsung galaxy grand quatro)
1. When you stand directly in front of a witch, it will miss every potion it throws at me
2. Witches aren't affected by harming nor poison poitons (not sure if this is a bug)
P.S. if this is a known bug don't blame me blame yourself, there isn't an option to directly search for the bug I want to report and I don't want to scroll 10000+ reports to see if it was reported or not
