Pixelmon Tokens vanishing after Log Off

1. Your IGN: Kaiser1417
2. Gamemode Bug Occured on: Pixelmon
3. Description: Apparently my token balance doesn't stay when I log off and then get back on. I had around 500 and now have zero. I noticed the same thing happen yesterday when I earned like 20 tokens and came back on to have zero, but just didn't think much of it at the time. Not sure why they aren't staying, or if the problem is happening with other players.
4. Image/Video (optional)
The screenshot just shows the zero balance.
