We've been investigating that pesky rollback bug players have been reporting, and finally tracked it down! We're happy to report that players should no longer receive excessive rollback in Crew Battle mode. We also improved re-queueing with a Team of Friends and fixed a few other small issues in this hotfix:
CREW BATTLES
Fixed a bug that caused excessive rollbacks when playing as a Team of One or against a Team of One.
The rollbacks were caused by a discrepancy between hurtboxes on the server and client, making the client say you hit things you did not.
Fixed a matchmaking issue that made it impossible to matchmake again after your first match when re-queuing an existing lobby of 3.
Fixed a hang that could occur when spawning the next character in a lineup inside of an article (such as a Kragg rock sitting on top platform)
In Doubles and Crews matchmaking, when matchmaking with friends, your lobby will no longer be disbanded after the match ends.
Bug fix: If a player gets KOd while grabbed, the grabbing player will now immediately go into the grab release state.
Previously, they would act as if they were still grabbing the dead player, and could throw them into the blastzone to take a 2nd stock from them.
Allow players to change their teams in matchmade Doubles (returning to the behavior before the mid-month patch) (For the people who *really* wanted to be on the Green Team).
Bug fix: Aerial Down Special will no longer crash the game when trading with another grab.
Down Special can no longer grab opponents who have chaingrab protection.
This prevents an infinite when two Galvans surrounded their opponent with Down Specials.
