Server lag is a problem lately.
Ur is overpopulated with animals.
I submit that an animal population reset would be a great idea. Players can repopulate the world and get badges going without the guilt of causing massive animal depression.
Rooks are making incURsions and taking animals away to feed an invasion force. They must be stopped!
Day 1: Aporkalypse
Day 2: Murder Most Fowl
Day 3: R-Day - Rook attacks, many simultaneous, all over Ur.
Give people a chance to try out their new rook-related upgrades, too.
