Will you make a seperate leaderboard for 2.0.0 times like Odyssey did for 1.2.0? Because I don't want to always have a bad time due to updating because I want to play as a new character.

(the pikmin exploit was patched from wol from what I've heard)

There are no details yet on what was affected with WoL, which would be the only sensible category to have subcategories.

Piranha Plant is unlocked at the start of WoL. For the first time they gave patch notes for every affected character but Olimar is not there.
