It would appear from limited testing that piggies do not feed from trees on our new housing streets, meaning that unless you feed them they die faster :( When I had a meadows house this was not the case and I was hoping we could keep piggies on our home streets if we had trees (other than wood planted) Also garden piggies dont eat dropped food or feed from the trees, it maybe just that the streets and gardens are new and so not functioning fully but thought it was worth reporting in case.
One other thought could it be tied in with the new sticks? Are the piggies just so happy they forget to eat?
ETA: Ok I tried with a crop rather than with grain and the piggies ate the dropped food, doesnt explain why they are not eating dropped grains or why they are not eating from trees.
