My army troops all together can hold 190 troops. I only attack frequently during wars and the rest of the times, I do farming. I've had two experiences where my troops go missing even though I didn't even donate them or use them.
1st case (2 weeks back): While I prepared for war, I trained three dragons in my army camp. When the war began, I found out that I have lost a dragon with a couple of giants.
2nd case (Recently) : (Since I donate too much, most of the times my army camps will be full of barbarians and archers. Sometimes a few wizards and rarely I keep giants .)When I tried to donate 3 giants to my friend, I found out that all of my 14 giants and 3 hog riders have gone missing.
I have a bad feeling that this might happen the third time also. Does this happen to you? or What should I do to overcome this problem? I love this game so much and need a solution for this problem.
