In answer to your problems, the link above (
@JNR90)will get you the walkthrough, I would recommend the 'Larry5168 'grindthrough' for a more comprehensive list. As for your second problem, IT greatly depends on which version you'r playing, if it's the 0.8.3'Test'version, then that has loads of bugs, if on the other hand it's the 0.1.82extras, then I can only assume that at the begining you decided to use the 'In Phone' cheat menu and selected the reveal all memories option, not sure if it can be turned 'off' once activated, if it can then presto, if not you may have to start again. hope that helps.
