Viktor bug, aimlessly walking forward after casting

Dear Forums,

Today I encountered a bug while playing Viktor in midlane. I have not played this champion often but this struck me as a gamechanging issue. While trading with my enemy I casted spells including my "W" and "E" in the southern part of the middle lane. After casting and my enemy laner ward-hopping away, my Viktor character aimlessly continued walking forward well into turret range. This obviously led to a kill by my enemy and changed every aspect of the lane was progressing. I have not managed to reproduce this bug but I would suggest it would be something to look into.

Thank you in advance
