a solution would be, check the logs on wednesday ban people for like 3days (you can't realy perm ban them since lack or player base.)
Than for pet pack would be just keep it as it is, but when new Pet aura and talisman stages came, make it from than on forward like a new pet pod currency like pet pod 2.0 or something. so people can get max with the current stuff but when new stages come they have to get the new pet pods.
I think this would be for the best, so people wont cant max talisman and pet aura stages when the new tiers get released
