I have noticed several times when clearing jungle camps, that when I try to lay a shroom directly on top of the minion I lose the shroom charge but there is no animation. I also believe that the proc is not applying. So to counter this I usually walk away a little then lay the shroom so the minions run into it. I used to lay shrooms down on top of the minions before the patch with no problems.
