The game just took close to 20,000 sapphires without my approval. 

I was reviving a small amount of high level troops (25 to 50 of each or so) that I had lost and suddenly when I clicked yes to acknowledge the revival of one icon, the troops were still listed in the infirmary and the icon for however many thousands of archers had been removed and were revived when I never clicked the archers icon??? I am suddenly down almost 20,000 sapphires?? I don't even know how many archers there were in the infirmary, but I am guessing 5 to 10 thousand?

These sapphires need to be restored and the archers put back in my infirmary. 

But more importantly, how and/or why did the game restore something I know I did not click ?
