    - Parry stun is applied properly to players landing with aerial
    - Parrying aerial attack now puts opponents into the helpless state, and gives them extra landing lag
- Players can no longer create profiles with no name
- uspec_bowser can now grab ledges during endlag
- jab_chrom can no longer be parried
- The tech buffer no longer deletes the shield input from the input buffer
- Fixed an issue where players could break out of grabs during pummels and not be launched away
