Troop revive? I believe there is a built in bug, that causes the spending of drac's.
I have tried reviving my troops, one to ten at a time, as an example, only to see the entire group get revived, through no fault of my own. As soon as I activate the "revive" button, the entire group jumps up to the maximum, causing my bank to reduce by ten's of thousands of drac's. I am one pissed customer! If the game can't be trusted...if the owners of the game can't be trusted, by allowing this to go on, why are we spending money here? I might as well go buy a few pints.
