I experienced a weird glitch(?) yesterday while playing Falcon dittos on DL. So like a peregrine falcon, I descended upon my prey, the opposing falcon. I read his jump and I dair him down into the leftmost platform. I wanted to do a tech read, dair again, and Falcon Punch. Instead of him landing on the platform, he slides off of it because of the angle that dair sends a player, this is natural. The weird part was that right after I daired him and he slides off of the platform, I shield 'cause I'm going shield jump or whatever but he follows up with a dair simultaneously. When my shield and his dair connected, I heard another hit sound as if he landed the dair but I was still in shield and I received no damage.
Did the game falsely play the hit sound because I shielded on the same frame that he daired? It was strangely similar to a parry and looking back I should have tried to act out of shield to test if I had shield stun.
