Firstly, if someone adds you, but reaches 100 friends before you accept their request, you'll get that error screen.
But I was getting the error for every friend, even immediately after they added me, so I thought something was wrong.
Go to your friends list, then scroll down to the end. I had a section of "Friends without The Simpsons Tapped Out" that I'd never seen before. Like these people deleted the game but were still counted as your friend for some reason? I don't know what this was about, but I deleted or blocked (only because there was no option to REMOVE FRIEND for some of them) and then I was able to add people to get my ACTUAL friends list to 100.
Very strange--I'd never seen that bottom section of friends who weren't actually my friends but kept me from being able to add other friends before lol.
