True AssasinMaster. If you're close to getting a badge and want a break, it gets erased. And if you have useful health on lvl 11, then you get half of all the turrets and 4 tanks, and if you start out with 85 then you're lucky if you have 5 by lvl 12.
Sucks. Die once because luck hates you (Seriously, I had to get a sun and a moon on level11 right next to each other.) and start over. I hope you die in a fire.
The annoying thing about this game is that no matter how much you ask, they're assholes and give you no help with the badges, and rub it in your face...
