lol i like your game - its great!!!
I have played it for many times... so i found a bug in the latest version:

this trooper get "boring" so he began (without i have done something) to build all visible buildings on this screen without increase the resources... if he had finished one he began the next. I have clicked him and ordert him to go away - so he stopped to build - he was still a "normal tropper again. It was possible to create units at the barrack.
Hope you will fix this bug - good luck^^
