I just checked in with Brabinger; he said "Oh, I have 1 Pumpkin Pie, but I don't remember who gave it to me. It must be for you!" and sure enough, there was a pumpkin pie!
Bug, feature, easter egg? Is it a real gift and he just can't/won't say who left it, or is it like a random harvesting drop? There was also a message (no gift attached), and I had given him some panini to hand out, at least one of which had been claimed, in case any of that makes any difference.
And if it was you who gave it to him to give to me, thank you!
