I went of and did /rewards and clicked the link. It brought me to the webpage, and I watched the little trailer. Then, the three cards appeared, and I clicked on one of them. It then said to head back to the server to get the reward, but only in didn't have it. I did /reward the next day, and nothing happened. And now today I did it and, guess what, nothing happened. It never asked my for my username, so that may be the problem, and it's also worth noting the first and third time I chose a Grepa Berry and the second time I chose a Hondew Berry.
