[GAMEPLAY] Aatrox Q and Scuttle Crab Bug

As any jungler should know, Scuttle Crab's MR and Armour get lowered to 10 when hard CC is applied to them (Elise E, Vi Q, Krugs stun, Nautilus passive)

However, Aatrox's Q (Dark Flight) does not apply this debuff to the Scuttle Crab and the crab still retains its 60 MR and Armour.

Steps to Reproduce:

Play Aatrox on Summoner's Rift Land the centre of the Q onto the Scuttle Crab (make sure it knocks up the crab) Notice the crab's defensive stats do not change.

This surely is a bug as I see no reason why Aatrox's Q cannot debuff Scuttle Crab while virtually everything else can.
