[GAMEPLAY] Malzahar Voidling No EXP Bug

I was playing Mazlahar and noticed the following bug: I got 0 exp from killing the buff and jungle minions when my voidling last hit the minion and I wasn't close enough.

Example: I went in to kill their jungle at lvl 1... got the kill... then proceeded to finish taking red buff and the 2 small creeps next to red buff and was still at lvl 1 after killing a hero plus the whole red camp. The distance from the plus the fact that the voidling was the one that last hit all the camps prevented me from getting any of the Jungle exp.

Not sure if this was intended but I would like the last hits from my poro voidling to give me exp.
