To open the next chapter you have to send one of your sims to the rainforest. This whole chapter thing is a separate quest that is completed in sections as the community gets to each chapter.
I have had a sim go to the rainforest, explore the X and place some flowers.
I now have to collect flowers and it seems like i have to collect 3450 flowers and 40 constructor coins to unloock the Crackling Campfire !?
I have +5000 flowers and 55 constructor coins and nothing is unlocked?
Try rebooting your device and/or restarting your game app. If this doesn't work then you will need to contact support. http://answers.ea.com/t5/The-Sims-FreePlay/INFORMATION-The-Sims-FreePlay-Support/td-p/1877383
Thank you 🙏 It seems like the problem solved itself 😊
