Wall jump tossback bug [GAMEPLAY]

So I just got out of a normal game where I was gnar and roamed down to help my eve against a vlad, we killed the vlad and then urgot came to get us (urgot was really good and crushing me in lane) and so i used my hop to get over a wall, but as soon as I successfuly hopped over it, I got thrown back and he killed me. It wasn't a ranked game, but it was extremely upsetting. Urgot snowballed from there and our eve got upset and afked, this but may not have cost us the game, but it really sucked, please look into it.

to recreate: step 1: be gnar (maybe other people that can jump walls) step 2: get mega step 3: jump over the center back of baron wall

I have only seen this once happen to me right now
