This event comes with a set of new quest conditions, one of which requires productions to come from buildings of a specific level. Level 1 Manufactories and Workshops won't suffice in this case, but you're certain to be successful with these quests if your buildings have been updgraded at least to the levels that became available with the previous Chapter in Research (or if that Chapter didn't contain Research for an upgrade, the Chapter prior to that). The amount of productions required by these quests has been lowered accordingly.
SERIOUSLY INNO????!!!!
This is your answer to our request to not have only boosted manufactories as part of the questlines??
So let me get this straight... you want us to have efficient cities with maximum use of available space, because you refuse to give us more expansions. We try to do just that, by using the offered event buildings. We let them produce our goods for us and delete our manufactories and residences in order to save space, and thus trying to be as efficient as we can with the limited space that we are given.
Same as for workshops, we use event buildings and magic workshops (bought with diamonds, your number one source of income) to get enough supplies while using the least amount of space. And by doing so, we are able to delete our regular workshops to save space for other things.
But then.... you decide to change course AGAIN and force players to have fully upgraded manufactories and workshops instead of lvl 1 manufactories and workshops for event quests??! Have you completely lost your minds?? Again?? Wow... You are really trying to get everyone to quit playing this game, aren't you?
