Blitzcrank pull bug

O.K. Hello Riot; not entirely sure this is a bug but I will explain in case:

When Blitzcrank pulls over a wall and he is as close to the wall as robotically possible the enemy pulled doesn't travel over the wall but stops on the other side of it because there isn't enough space for another champion where blitzcrank is trying to put the other champion.

I am not entirely sure but I think the same thing happens with minions directly in-front of blitzcrank; as long as the space directly in-front of him is occupied the pull does not complete.

I am a Plat V Blitzcrank main and have experienced this multiple times but my lolrecorder is on the fritz so I am unable to currently provide a video.

I will try to get a better recorder and use my VM to run two clients and replicate this soon!

Thanks for reading!

p.s. I don't know if this helps but it seems to have started when the visual update to SR was done and it only has happened to me on SR.
