why do i buy 75 speeds to get 25 more speed usage to win a mission and after one battle all speed is gone and im still short 14 speeds for a mission? why is it i get 300 mines and 300 speeds and they are gone in one or two battles...this game is so broken and this is why ill never spend money..i used to have thousands of mines and speed and they are all gone and i dont play that much..but i bought 75? i needed like 34 for a mission..after battle all 75 gone nd 14 more left needed for mission?
