[GAMEPLAY] Blitz grab doesn't work as intended

Hee,

I just played a game with blitzcrank support. I often walk up to the enemy jungle, camp in the bush and place a ward and grab their blue/red buf away just to give my jungler a heads up.

Last game I played against a shaco jungler. He knew i was there but he already had the boxes installed. I waited for the boxes to dissapear and the fear to wear off. Shaco placed a ward right in front of me. When i grabbed the blue buff (he was arround 600 health) i hit it and pulled it towards me. The problem here was that i couldn't grab him over the wall. The wall blocked my grab and shaco could just keep going on blue buff and take it.

I've done this many times and the blue buff should just go through the wall but it didn't. Players of the game can confirm that this happend. It only happend that one time. I'm not sure if its becaus of shaco and his boxes that this happend or something with the wards, but its really dissapointing that i wasn't able to grab it.
