Currently I'm the victim of a bug that the new pvp loot does not drop. No matter how many attacks I do I only get measly tree snipers and oil aircraft carriers. While other players get predator subs and defensive cannon. This has been going on for 6 weeks now and no resolution so I though I would compile a few of the other unfair advantages and disadvantages that seems to plague this game on a regular occurrence. Some in the favor of the recipient and the expense of others creating unfair balances in this game.
The Rivals list bug
Imagine never being attacked unless it was revenge for an attack you yourself perpetrated. Well, you do not need to imagine because it happened! For months some players were invisible from players' rival lists giving these hidden players freedom to amass millions of unprotected cash without fear of attacks and the ability to purchase and upgrade the most expensive buildings. Some were so confident they never bother upgrading their vault.
The Unlimited Energy Bug
Imagine waking up one morning and your energy was not depleting. Well, you do not need to imagine because it happened! Some lucky players received the unlimited energy bug giving them the ability to complete thousands of mission, haul hundreds of millions of cash, and thousands of loot units. Not to mention advance multiple and multiple levels in a matter of hours or even minutes. The players are to blame as much as Funzio for this one. Other bugs players have no control how and when they are affected. In my opinion however, Funzio should program a game where exploits like this shouldn't occur and then we wouldn't have to worry about dishonest players taking advantage.
The Residual Command Center
Bug or Glitch? Who cares. Some lucky players have an extra building generating cash for them. Potentially worth an extra couple million over the course of the game. I can't say for sure if they are able to collect from them, but from all reports they can and do.
