I just noticed that the resource cost for basic boost+ flag and the basic income and limit flags doubled as did the reward xp. I noticed this when I got to level 61 (didn't buy any flags at level 60 or 59) via the iOS app and, in a previous game, I don't recall the resource cost or xp increasing at any point. The other flags seem to have stayed the same cost. What's the deal? Can I expect the resource cost for flags to increase depending on what level I am?
