The default levels.dat file in the worlds folder that comes with the game when it's installed is outdated, and so is the one in the worlds zip that bunnybot5000 linked to here. I emailed Jamul about the bonus coin issue and he explained it to me with the latest levels.dat file attached, which I uploaded to mediafire and linked to here. If you want bonus coins to count for the shop after beating any of the approved community worlds in the zip that bunnybot5000 linked to, you need to replace the levels.dat file in C:\Program Files (x86)\LunaticSupreme\worlds with the one I linked to.

I'm not sure unfortunately. Try emailing Jamul about the problem. He had an easy solution for mine. jamul@hamumu.com
