I recently had my game Moonsweeper accepted. It came out for the Atari 2600, Commodore 64, ColecoVision, ZX Spectrum. When ever I add the cover art and the platforms it dosen't save when I exit the page as there is no save button

Are you positive you don't have a save button? For that section it should be under the "default view" option

Thx that worked :)
