wandering in rappam rolls, dug in a dirt pile next to the sign post on the far right side, when i tried to dig a second time i was told that i was already digging. i definitely finished digging the first time, even went and planted a tree in an empty patch. (don't know how i missed it before i started digging, doh!) just went back and tried again, but it still thinks i'm digging.
moved on to next street. was able to dig there. went back and was able to dig.
