Issue Description (10/10):

Please include the following information:
what I was expecting to happen when I clicked on my expansion tab once in the building menu was to see a picture of the expansion slot telling me if I had one available or how many medals I still required in order to unlock my next expansion slot but what actually happened was no information just a blank space where the image should have been…

Then you have used all expansions. Won't show up until you research one, get one on the continent map or reach next Era.. Reach next Era there will be more medal and Diamond expansions...
