[GAMEPLAY] Tahm - Using W twice fast on a Minion makes them incredibly tanky

When I do a fast double tap with Tahm's W on a minion/monster to clear the jungle fast, push the lane or poke instantly (so the enemy opposing laner cant react), following bug occurs from time to time:

The Minion/Monster does not get thrown, instead it plops out right in front of Tahm's belly. There is no following collision damage nor devour damage. I am not quite sure about the devour damage, because I've been mostly in a rush (that's why I used the spell afap twice).

I am not sure if the devoured minion/monster becomes incredibly tanky or just stays in stasis. It cannot move, receives no visual damage whether from Champs nor Minions (can be attacked though) and fights back.

I'd say it occures one to two of three times after fast double tapping creeps. Well, I learned that keeping stuff in my belly longer avoids the bug, but that took my ability to clear fast or fulfill surprise poke attacks. From time to time it still happens, (sometimes you just have to be fast and you do not think about the bug). Happened every game so far. I have to point ou, that I am only playing** Twisted Treeline** at the moment. So Idk if the Bug, also occurs on the Rift.

This bug is incredibly annoying. I died 2 times to jungle creeps. One time we could'nt push a tower, because of this fuckin unkillable cannon minion. Three times the opposing laner went all in after he saw my W went on CD for nothing and he won the following trade single handed. Two times I did not get a kill.
