GAMEPLAY

While playing Varus, amidst a mid lane gank, i flashed under turret, as a Tristana Ult (Buster Shot) pre-hit me, it should have placed me on the wall, but i ended up way far behind it, catchable to opponents again. I understand that a targeted skill always hits even if u flash, but what happened wasn't normal. the wall was way too thick for it to make me trespass. The precise location was a bit behind the middle outer turret, i flashed to that position to avoid colapse and the buster shot took me to the path to blue, the interaction was not at all fluid (keep in mind, bottom side mid-lane outer turret plus the tristana was in the opposite direction wich i think should have made me bounce deeper into mid lane and not the otherway as I ended up on the referred path). It only happened once but i do think this was a bug. Thoughts? thank you, Rokself.
