Experimentation!

I was wondering how we were supposed to have our characters INSIDE buildings...yet have them wandering around outside to get the mythical heart over their head....haven't had a single visitor / heart drop yet.

Visiting friends right now is like a little roulette game....will I see the Cupid Bart title screen or not ?

PS What's worse than tapping on a friends town and getting the blue arrow "old version" message ? Actually getting in to a friends town and finding no cards.... :?:
