Blue buff

Ive noticed if you stand to the to the side next to the wall opposite of the bush while dong blue buff you can get the buff minion stuck behind one of his little friends and the wall. It will not reset or be able to damage you because it is blocked off between the wall and a minion. Works better for ranged champs but some melee can still can utilize it. Could simply allow buffs the ability to walk through other minions. Also not really a bug but kinda bs that Kalista can stack spears on a buff and just keep letting it reset and it wont lose any spears so you can just pull a hundred million spears out of any jungle minion for the kill without taking damage. I Should also note ive only been able to do this on red side.
