@Toffer,
i was going thru stuff and looked at ur Neanderthal city folder, i think what it needs is to be incorporated into the CityLSystem also, just guessing here, dont know if modular stuff will work for cities??, thats what i had to do for adding in the PreH Era stuff, again just guessing, its been sooooo long, sorry. . .
What Neanderthal city folder?
You may be right about there being a problem related to CityLSystem; I shall devote some time investigating it. I find that stuff incredibly complex and confusing, hope I'm up to the task.
