I saved my landorus' set (u turn/stone edge/earthquake/explosion and jolly nature) at set master in vermilion city and changed everything including Evs,nature,moves of my lando but now when i want to load my previous set,the set master is saying 'you have no saved set on your landorus'. That means my previous set got deleted by itself. Is there any way to get my set back because i hv used a lot of money in changing my landorus' set. 

Kindly guide me.

Could it be that you transfered servers?

Sets are saved on the server you created it on. So if you created it on Gold for example and transfer to Silver it wont be there but it will be there to be loaded once you transfer back to Gold.

Ok thx ^^ i got it 

Have a nice day
