i was trying to upgrade the dragon roost to max and i needed 7 more dragons at lvl 35 to get it so i was trying to count hw much food will i need to do that so i pulled the old (before update) costs and then it got a bit confusing so i opened dragon city i went to check the costs and i found out that it's differnt after the last update (dragon roost..)
if any one has/know the costs please post them.
