Is that a bug or a trap to get easy money?
When we can't destroy a low level base we have to build another one and will cost a lot of resources. If we don't want to wait 1 MONTH (or more) to gather it we have to buy resource boosters or the resource itself and that costs GOLD! Then, we have to pay for gold cause those 5 daily gold are for nothing.
Guys, wake up! This game will be "beta" forever, full of bugs, just to get money from players. They are not interested fixing anything (the Depot bug is still the same after I have reported it more than 1 month ago).
