Good game but highly disappointing

I had this game for a long time now because I was chipping away at the longest mode of the Grand Campaign. There are few minor glitces for me but nothing that makes it unplayable… until I got to turn 460. After putting litterally months of work into conquering India, Africa and South America (Americas Theather) It wouldnt load my saved game for me anymore!!!! It told me my save file was corrupt. Like I said SO MUCH EFFORT BUT I CANT CONTINUE. The App Store really should do a better job at testing these converted game before selling them. Feels like I have been ripped off.
