I have been trying to get this achievement for quite a while. Finally I got to 95 / 100 drones. So I fried 5 more and refreshed the game. It still said 95. So I fried another 5. Still at 95 / 100. What's keeping me from getting this achievement?
I would like to add that I've been able to get achievements for other games, so it's only this one that's not working.
