[MAJOR BUG] Super minions inspire themselves

I dont know why super minions are inspiring themselves to gain increased damage and gaining increased armor and MR. Was this documented in ANY of the patch notes?

Steps to reproduce:

1. Pick champion in summoners rift. Pick tristana for faster pushing.
2. Destroy enemy inhib.
3. Observe your super minions stats.

The super minion should have 30 armor and -30 MR but has 100 armor and 40 MR. Furthermore, when two super minions pile up, they dont gain anymore bonuses. Riot please, look into this as it could affect competitive gameplay during playoffs(I assume). I noticed in one of my games yesterday that a single super minion took down my half health nexus turret with ease.
