Oh gree, oh gree what have you done to Android?
For those not seeing boss triggers, it appears or in this case disappears the same as cash drops on mission completions.
I just discovered you are actually triggering the boss but the screen telling you you did does not show up! That is until you log out and go through the session expired screens in the hope of getting reconnected. Then after going through all that crap viola, the boss screen tragically er magically appears.
This is well beyond an epic fail.
