Same I had the prometheus kit and vulcan mammoth m3 kit in my garage with well over 4 days left, when I ranked to generalissimo and suddenly they were gone and i only had 100 and 1500 supplies kit in the garage. :/
Generalissimo rank is bad you have only supplies kit 100 and 1500.
The others kits never come back for this rank it's a very bad thing of tanki you can have full m0 garage at generalissimo 0 kits so need buy items 1 per 1... that cost a lot ! need to correct that
