Cannot transfer my character

Hi, I recently made a character on my main server/data center (Siren) to give it some gold and items, and level boosting it with a Mogstation item before transferring it to a new data center where I have no other characters (Diabolos). I got an error that I needed to wait 3 days to transfer, but after waiting 3 days it now says I must wait 90 days.

I searched to see if anyone else had this problem and it seems a new rule was created that will not allow transfer from a preferred world (I did not know this rule, nor that Siren was preferred at the time of creation). I wanted to know that since Diabolos is also a preferred world, could my transfer be facilitated by a game master? If not, can I have a refund of my Mogstation level boost so that I can buy it again for a new character which I will create on Diabolos?
