[Gameplay] Rammus glitch with Mark

Over many games of ARAM with rammus I have continued to experience one major issue with using Mark. The issue is that when I hit someone with Mark and initiate powerball then proceed to dash to the person who I marked, if I hit a champion or minion during the Mark's dash that is not the person who I marked Rammus is sent flying high into the air. The farther I go before hitting someone during the dash, the higher I fly. Probably the biggest issue with this is that while in the air I am still targetable to towers. This has happened to me many times already.
