I've been getting blank items in vendor's inventory (hardware vendor, several items), my inventory (test tube bought from hardware vendor, piglets hatched from piggy eggs, shucked seeds). These are all items I have newly generated in the last hour or so.
Also, I just fed the two piglets into piggies in my backyard and although my local chat has two entries saying "You fed a Piglet. It grew into a Piggy!" (10:37pm and 10:38pm GMT) I now have only one piggy in my backyard.
