Here's the map in question: https://mwhite.cartodb.com/tables/where_good_neighbors_work

Our map had been working beautifully for several months, but when updates were attempted recently, all of our locations were somehow changed to the same longitude/latitude point. Basically, I want to know if we need to go in and fix all of them by hand (I cannot get geocoding to work anymore using any of my table's location criteria, though it worked fine before. I strongly suspect using geocoding might have caused this problem in the first place, but I can't say for sure as I was not the one who used it this time).

Anyway. If there is some way of automating the long/lat fix, or possibly using a proverbial “back button” to restore the geodata we had before, I would like to try those options before going through the labor-intensive process of correcting them all by hand.
