Please help! I've got all of the required, suggested, and other recommended mods installed. While I'm in assembly my top stage has fuel, but when I launch, it's empty! I've tried replacing the part, using different tanks, using different fuels, different levels of fuels. I have no idea what I'm doing wrong and have tried searching for other people having the same problem but I can't find any info. Any help would be greatly appreciated. http://i.imgur.com/XbMKeMd.jpg (fuel in top stage) http://i.imgur.com/vBrnouz.jpg (no fuel in top stage)
