I have a pet piggy at my house (a generous glitch mailed me a piglet) and today I witnessed a second instance of a strange behavior.
I had been gardening for a few minutes. I dropped some potatoes on the ground and the piggy said "yum" and came closer and ate some STRAWBERRIES.
I have crops all over the ground for him to eat, but it seems he doesn't consider eating them until I drop something. I don't have the RHK skill necessary to have a feeder, so I do a fair bit of manual feeding (mostly to get seeds).
I wonder if there's a defect in the piggy self-feeding logic that prevents him from eating crops on the ground until a player action triggers it.
