I came on to vote about an hour and a half ago, and the first time didn't register for some reason, as I was able to go back and vote again after I saw I didn't get the NX from the first vote. The second time worked, but I received 16k NX instead of the usual 8k as if the first try had caught up and combined with my second try. I don't know if it has something to do with waiting for GTop100 to refresh to the home page after voting or if it's on the Royals site's end, but I figured I'd at least bring it up since this could easily be abused if people figure out how it works.
Can you give us a character name on the account you voted on? So we can check some logs to see what exactly happened.
