update: need help LOL

hi!! i literally just posted asking for tips on where to start with decorating your island. unfortunately i just discovered what i think is either a bug of my game or a major oversight on my part.

to unlock terraforming, your island has to be 3 stars, which requires kk’s concert, which requires a campsite. i went to tom to get a campsite, but he only will speak to me about bridges and inclines. i read through someone else’s post with this same issue, and saw people saying something was wrong because they only have 5 residents, not 10. this is the same on my island.

i really don’t want to have to reset:( is there anything i could’ve missed or any fix for this? all the original residents houses were complete, my house is nearly 100% done, as is my museum. i just hope i can fix this lol. thank you in advance :’)
