Possible bug: I have noticed that I haven't had the option to water or pet the egg tree I have planted in a patch in my front yard for several game 'days' - I can still harvest eggs normally each day, but the water/pet options are greyed out on the menu. I don't recall how long it has been, alas, but I remember it first happened yesterday (4/26/2012) in Real World time, probably in the afternoon. Using Chrome on MacOS 10.5.8, not sure what else you need to know.
