I found it all the ways down on the bottom of the list of supplies at 3am today (tuesday).
I have no idea what its for can’t find anywhere on lil green patch that explains what its for.
I had it pop up today, someone grabbed the pot of gold from my patch. I clicked on the map & it took me to the patch of the person who grabbed it from me but, someone grabbed it from her so I clicked on the map again & it brought me to the patch of the person who grabbed it from her. I grabbed it from the 2nd person and its back at my patch now.
