Right now I have a max population of 105. I achieved this with the Magic faction and after completing the tablet collection. I don't know if it will go higher since I can't find the other 3 missing pieces to my other collections. The chief points them out but darn if I can find them. I find all sorts of pieces but not the ones I need. I will keep trying every 24 hours. Started a new tribe so I go back to my first one periodically and look for the collectibles.

Just read the posts after I posted this so it is the collections I will keep at it!
