I’m not in game atm so I can’t post a screenshot. My current build has 18 hearthlings and my last build had 22. The number of hearthlings you can have is dependent on your computer more than the actual game. If you have other programs running or your RAM is getting full you’ll be hard pressed to go over 15 hearthlings. Once you’re over 15 hearthlings you might find it works better if you reboot the game every half hour or so to clean out your ram and keep bugs to a minimum ( I learned that after losing several towns to game breakers lol)
