I'm a bit confused. I know I did Archaeology on Beta. I'm fairly sure I didn't do it on the main servers. Yet the forum announcement says it will start on 23 March (okay, they do say "on Beta" but there's no other indication of when to expect it).
I do hope they've made changes to the butterfly group. It's a very pretty event building, but for the size, the rewards in the Beta version were just not worth even half the space.
I agree we need to stay polite, but also understand the frustration of all of us who play, make suggestions based on spending WAY too much time playing this game, point out inconsistencies and other problems - and seem to be totally ignored by the devs. A monthly newsletter - a page will do - from the actual dev team stating "we're working on x, y, and z" or "this is why we can't do [insert idea]" would be helpful. It would be even more helpful if it is not posted on Facebook, some of us detest FB and avoid it like the plague. (Ditto Instagram, TikTok, all those wonderful apps that track us better than the NSA.)
