Please fix crashes – Civilization Revolution Review

Its driving me crazy; don't get me wrong, for a mobile game this is 5 stars but whenever I do something major it'll crash. For instance, whenever germany declares war on me and I say: "Bring it on.", I crash. My culture advisor pops up saying hey! need 12 more things! *Crash* I keep restarting, re-installing and it keeps crashing. (I run iOS8/iphone5)
