After the last test, life cycles for things that grow (like trees and piggies) were not turned off as soon as the test ended. This is something we normally do, but didn't for a few days after. Depending on the health cycle of the tree or piggy, it may have expired in the game. You may see extra meat and plops around the world, or higher than usual number of trees that need clearing (including your home). If you had piggies in your home you want replaced, just let us know.
