Instead of watching aspects of the game crash I decided to put on my face mask and go on another forum crawl. It's dusty down there!
Big Al gave us the clue in the very beginning, eggs, and I was a little slow (faceplant) in the uptake.
Easter 2014 and 2015 introduced a new GB, new special buildings and units, and a new kit. I won't spoil it, but it's hard to imagine the game without some of these.
It was changed in Easter 2016 and the ability for a player to gift eggs to other players was discontinued. Instead, it was a familiar mechanic of event quests, daily pick up (then in town hall) and incidents awarding eggs. The eggs were then used to open chests to get tulips to make progress towards a Grand Prize, and they added a changing daily special.
I wouldn't mind playing an old-style Easter event. The mechanic of being able to send a gift from my city to another (at least an item/object that the game has given me) could lead to interesting possibilities for events with a little creative thinking.
Instead, seems like the route chosen was ever-increasing complexity and cleverness, culminating in St. Pats. Ugh.
