So this happened during the last test and I was waiting to see if it would correct itself, but alas not.
In my backyard, I was feeding my piggy repeatedly to get some seeds for my garden. Not sure what I did but one of the plops fell all the way to an unreachable part of the screen at the bottom. I was only doing one at a time - I'd feed, pick up the plop, pick up the seed, then feed again so there weren't multiple plops or seeds on the screen when this happened.
