I'm wondering if non-merged servers get their prizes first. Or 4/5 winners cause it's a statue. 1/2/3 they'd have to check for what items they picked.
I went from Pande to Asura and had to change my name. Insanely lucky to win Rank 2. I hope the server merge didn't disqualify winners. According to the official Vanafest website for Nomad Bonanza it said it could take some time after update so maybe in the next couple days we will know?
Maybe using your SE ID and token may make it easier for MHMU to track winners down?
