Oh boy ...
Players that had not joined yet need a reset.
Players that had already joined and win got the medal.
reset or not will make one side not happy. not players fault but the system.
My advice to the system Admin:-
1) Take back what the winner have and replace with medal of doom or create new medal of early bird (+1 luck or one level 1 healing potion everyday)
2) put another schedule back for this Blood championship, and take back Blood medal after 15 or 30days later, before next championship start.
I am also not joining yet, but trying to get the issue resolve and move on. just a suggestion, if consider, some tips to me is appreciated.
