Jenny - I saw your list of the Testimony locations which was very helpful because it confirmed a bug I ran into which involved the testimony by the safe in the beach house. I picked it up and read it...later exited the game but when I returned to the game and was about the cross the rope to the temple, I only had 87% of the testimonies and was missing one.. going over every step, the one I didn't have was that one AND it was not under the safe anymore !! I continued without it - bummer!
I had the same bug the first time I played, which is why I replayed and made the list (originally only for my own use, but then I thought other players might be interested in it).
I don't remember for sure whether I ever saw the testimony under the safe in the beach house in my first playthrough, but I didn't see that particular testimony among my testimonies in the game. I also had a weird bug where testimonies would reappear after I exited and reloaded the game, such as the one on the pier and the one by the bridge -- pretty much all of the ones that you didn't get automatically when you picked something else up. But unfortunately the one in the beach house never respawned (assuming it was ever there at all). This may be a bug that happens if you do things in a certain order. Or it may be a bug that happens if the game randomly puts specific testimonies in different places. I didn't have the bug on my second playthrough.
Thank you all for the help, and if I could get that saved game after the minesweeper puzzle - that would be great !
I'm unsure if saves are transferrable, and since there is an autosave, you'd need the save from someone who exited the game after finishing the Minesweeper, but before going on to finish the game.
I'm going to replay to check that the testimonies are the same between games. I was going to skip the last bit (with that awful Minesweeper), but I'll see if there is a chance to exit the game after doing the Minesweeper.
Autosaves seem to be in
