Donuts from visiting neighbours after the update

I got Stampy about 4 days ago and today was the first day I found a donut while visiting friends.

I want to keep track of where I find donuts to see if there is a pattern or limited locations. Today's was found while clicking on Flanders house. I wonder if you still have a chance to find donuts in KL as I will usually check out KL if a friend has nothing to tap in SF.
