If you're stuck on "Let's split up, gang", you don't have to wait on Olga. The place where the final clue is is available as soon as you get rid of the lizard. (Just go up the path to the left of the ruined bungalows.) Once the "Andrea's unwanted visitor" questline is complete, it will trigger a quest that will lead to finding Tori. Then you just have to wait a few days and Olga will ask you to rebuild the bungalows.im having the exact same issue even bought all bikinis and lingeries and saw all the scenes with all the girls to see if olga next quest triggered and nyet. this sucks man, trying the game for the first time and being halted in progression by an aparent bug.
The problem right now seems to be that some people can't go up the path leading to the vista. Which looks like a bug, if we assume all the people complaining about this aren't just having a special moment.
Also, it's probably platform-specific, as I can personally attest not having this problem with the latest stable build on PC.
