As the title states, there's a bug with Annihillus and him placing Stifles.

As you can see here, his abilities state that whenever he place an ARMOR BREAK debuff, he also has a 100% chance to place a STIFLE debuff.
My problem is... how is this possible when the champion I use is ARMOR BREAK immune (Sasquatch)? He also placed a STIFLE on my Colossus who is ARMOR BREAK immune to all classes except TECH.
Kabam?
