There are known issues with the accuracy of the walkthroughs in the mods, due to changes having been made to earlier events in the game.
Which is why there are multiple posts in the thread from people having issues and being told that the mod is no longer any good for the walkthrough feature.
Version 17 is due to be released very soon, and it has a built in walkthrough feature, so no mod will be needed for it for that.
Downside: A known glitch is that saves made with the mod installed, more often than not will no longer work without the mod installed.
Best bet, is to stop where you are, and wait for the release of version 17 and start the game over, without any mods installed.
That way you will get to see the newest changes to earlier events in the game, and not have to worry about inaccuracies in the mod, messing up the game. (There are more changes included in version 17.)
