since easter event BB introduce this thing that every one reject it and it's the multi buildings to increase production speed,
and tbh i still don't get the point of this procedure and how to increase production speed with the 2nd building,
but the funny thing -and the main proplem- that this procedure repeat itself in every event after (snack stand, laboratory, scoutin post, training grounds, and now in xmas tree) and most of them take avery big space.
BB please stop this thing or at least make the 2nd building as arecipe to the main one to increase speed
