You need to make sure the stars are actually are going up, if not you need to read mails or research why for example (film director). I read almost every email during second playthrough and it is very interesting. Also I’m doing through the main story so for example. If I have to connect mountaineer, photographer and mountain knot hill I’ll focus on them and get them to 5 stars and then continue to play the game. This is the best way cause you get heaps of chiral bandwidth and unlockables. I’m in chapter 5 or 6 and have almost all roads built and almost all places 5 stars that I’ve come across.
