Has anyone been able to figure out how this Valentines event works? I keep swapping different love letters from different people but can't seem to figure out where that ends up. None of my citizens are giving me any of the items needed to build the three required buildings. All the citizens are offering is the card swap. Am I missing something? EDIT: Ok I think I figured part of it out at least. Looks like we get a card from Alex then trade it for a card from Emma which trades for a card from John which finally trades for a Love Arrow. And we need 300 of these arrows to build the Post Office. What. The. Heck?! This will take like 12787282893827823 years to complete. EDIT#2: I was able to find one solitary citizen who gave me a letter from John, which I traded for an Arrow. So, there might be some out there that will let us skip a few steps, but those I'm sure will be few and far between. I also noticed some backwards swaps so people be careful about what card you are receiving in return.
