Facing a complete restart using the ps3 trophies guide instead as, like most others here, I was missing the two tips. Managed to fluke getting tip 87 but cannot for the life of me get tip 54. Hopefully the other guide is accurate as I am not doing a third playthrough.
EDIT : One other thing. Don't quit out the game for any reason, you lose all your fucking auto saves.
EDIT 2 :- All done. I used the Ps3 trophies walkthrough to do another playthrough. As has been stated before, you need to select both options on the timeline the first time to get tip 54. Just select the first one, let it play till the next option, then go back to the timeline and select the second choice. This will net you tip 54. Sadly, I cannot remember how I got tip 87 to unlock.
