Sion W Bug

Hi, found a bug on Sion that causes him not to gain the 10 bonus health from his w from large monsters and cannon minions for the rest of the game. The Bug occurs if you start a jungle camp at lvl 1 ( raptors for example) then go to redbuff to get executed and steal it with your passive. You sart q and clear the firt camp (you wont get lvl 2 ofc) as soon as you reach red you get executed and kill one of the small creeps giving you lvl 2. Now you put a point into w ( ofc because you can come to lane with 12 hp extra) but strangely you only get the 2 bonus hp from the small creep and not the 10 from redbuff. Also this does not go away for the rest of the game. You will continue to stack 10 hp from kills and assists on champions but not from cannon creeps and large monsters.
