When I first read about the adjustments for the older event buildings, I thought it won't bother me, because I started later- tuns out I was wrong. I went for the Father Tree of Candy Cranes in the last winter event, because they give as much population as residences two chapter later. Now I'm in the next chapter and they'll give less than my current residences when the change comes. I gonna loose more than 1k population alone, that's more than my current population and half my total once I deleted the extra buildings I built for this Adventure. This games challenge is to balance population and culture on limited space to build and upgrade buildings. That's why I decided to go for hybrid buildings with high population and that's why I spent money on the events to get more of them, thinking that the money is well spent since the game is straight forward and it's been anounced that event buildings will become upgradable. Now I feel tricked into spending money under false premises, because the upgrades for event buildings will only be available once the value will be reduced. I'm sure there are many players who started playing after March 17 like myself who still haven't realised that talking about adjustments to pre-March 17 event buildings means talking about current event buildings as well, because they are still given out- quite a few of them appeared in the previous winter event alone.
