Hackers everywhere.... this one found in Taiwan server. The administrator is investigating...
That's not a hack. It's the servers reacting slower than you can click to add bases. If you go to add a base and the server doesn't reply instantly, you can go back into the shop, and if you're quick enough, still have the option to add yet another base. You basically trick the system into thinking you have 4 bases while you add both. When the server finally registers it, both are built. The same thing can be applied to buy upgrades without having enough gold to buy both, or buy spells. It's very poor programming. Not hacking.
Exactly. I have seen this happen many times when I'm on a laggy connection. The server reacts slow to the actions you have made in the game.
I accidentally discovered this bug when I was upgrading my level 9 walls to level 10 (100k each). I upgraded 5 walls (total of 500k) when I only have enough for 1. When I finally realized the games was lagging, I wanted to restart the game. Before I could do that, the server responded and all 5 walls were upgraded. My money went to 0.
Either the servers dont have enogh capacity (bandwidth or cpu wise) or the code is not good enough to discover such an anomaly (person of interest?).
But sould be a checking mechanism sometime when you play to rollback such a "trick".
