I haven't tried the mesh displacer on these guys yet, being in constant anguish about the file to corrupt or some other error (in a previous file, I couldn't edit the instances anymore after a certain point). Just very carefully building this up, so no real messing about. I'll try some buildings to distort in a separate file, though, thanks for mentioning it again.
Annoying detail; I made the stone market building because I was told so, then another archeaologist came about and told me it can't be there, must be another building....mmm.
Organizing the network is important. You can group objects, give them additional names for easy location. But there aren't that many objects here yet; mainly pops.
