So, normally I don't come for help unless I've expended all of my options, but I've been working on a map of my hometown, which is a 5x5 cell region. I generated lots for all the cells and got ready to add the first building, so I double clicked on the cell I was to add the building to, but it comes up as a blank cell, just a grey region. I'm not sure if I missed some step, but I've gone over it a few times and ran a blank. Thanks for the help.
