Maybe you haven't read my message carefully. This problem already existed since the first time they gave us such types of buildings, precisely with the krarak event, where some buildings had a basis production fixed for everyone, and not based on boosted goods. At that time some players obviously noticed that the basis production of some buildings was the same type of their boosted goods, and so the effect of the mountain halls was applied on them. So the question was: "is it a bug? well it's quite unfair that some players get a boost in an event buildings thanks to that!" OK, what was the answer by the moderators? "IT IS RIGHT THAT THE MOUNTAIN HALLS IS CONSIDERED".
Now I agree with you that is quite unfair BUT the moderators said it was ok and in fact this was not corrected! Then other buildings that give fixed basis productions came out often after this, quite every event!
Then also the Aureate Phoenix came up, which basis production IS NOT marble, but COINS. The boosting is related with the temporary effect and it is applied on others buildings, and it is added to the effect of MH upon that same particular event buildings, within those 3.5h. Indeed no one reported it as a bug.
What I say is, you CANNOT fix BOTH (if it was intended a bug, and it was not) now, they should have done this immediately months ago, without creating other programs of possible buildings that could have been boosted thanks to the effects of MH and AP, because players would have react to this.
I always asks myself why the hell moderators never answer me in my questions here. Have I some type of contagious disease?
