it is not that you lose your army, well it is like this for 4 months now I have been playing nothing but the Persians. 4 months ago I was on a huge run for a month straight where I converted 100k in def units and about 5 mil worth of off into a 50 mil off and 60 mil def. I did not stop playing and I kept going then one day as I was playing I ended up knocking down probably 80 positions, and got no reward over 500 units. so basically this took all of my army which was gigantic. since then as I have been playing I only get off rewards and none of those are more than 12-15k which is good but no where near the force I had, also I have knocked down at least 50 def positions since losing my army the first time and have not got any rewards. now I am stuck with an army of off. I have tried everything money, math, waiting, playing dumb, playing every event, tournament, I raid for 100k each time, I complete every daily task in the personal events. so no matter what I do in the game it seems to be locked up on me getting any rewards back. so now I can either quit playing the Persians and wait two years to build 10 mil in def or I can jump from one coa to the next or just play by myself I guess. either way if you are dumb enough to send your whole army to the Persians it is your fault, my mistake as well, and you should be punished I guess. either way the Persians have a built in infestation in them so if you lose it is gone.
