Incompetency
Funny how every update they have to take down the servers because they don't know what quality assurance is. Even more troubling, if a situation is beneficial to the player in any way, immediate maintenance. If a "bug" is in their favor i.e. a.i recovering faster than it should, "deal with it we'll get to it when we feel like it".
We are not your beta testers, do your own in house testing before rolling out any updates on live servers. The fact they dont know this yet screams utter incompetency or willful ignorance. Put half the effort in the rest of the game as you do in you "sale events" and maybe the state of the game wouldn't be as big of a joke that it currently is.
