Hi I'm currently trying to upload my game but I am getting this error, "Zip contains file extensions not on the whitelist". I exported the game using Scirra Arcade method, and I'm using version r85. I am not using any third party plug ins and after a couple of look backs I think I have all of the correct behaviors.
Granted the game is 10.6MB, but I would have expected a file size too big error. If it is the case that it is too big I'll try to cut something out so it can fit.
