Variant 2.2.1 bug

I was using my Hyperion which is a large champ against the stun immune green adaptoid, with the intention of sp3ing adaptors to death. I use an sp3, then my Hyperion just dies instantly. This should not be possible as large champions specials cannot be glanced, please fix this bug. Attached below are screenshots of relevant information, if there is a suitable explanation please enlighten me.
