-Fixed a bug causing players to lose 15MMR when failing to join a ranked co-op lobby.

-Players could enter the run while their partner remained stuck in the lobby after Ranked MMR had already been deducted.

-Added safeguards to co-op lobby syncing.

-MMR remains hard fixed until both players confirm their first handshake with the server and upload their ghost snapshot on their 1st battle.

-Players who unfairly lost MMR to this bug I have manually restored your lost MMR.

Thank you those of you who notified me of the problem.

as usual, please report any bugs to the suggestion box or the forum and i'll investigate ASAP.
