Well, the objects blocking the path were removed with the mod--they simply shouldn't exist--so if you're 100% certain that you're in the right place, I would assume the problem to be one of the following:

- The saved game was one made before installing the mod.
- There are other mods conflicting with the mod.
- You are using the developer edition of the mod and some files are misplaced.

Can you tell me where to find the extra area?, I must be going slightly mad because I can't find it and I am not 100% on the spot.

There is a large puzzle within Phantom Forest, in the northeastern portion of it (the one with the large boss-demon that guards the door to the source temple).
At the northernmost part of this area there is a portion of the puzzle that has you move three statues onto specific platforms--at the north edge of this area, you will find the opening.

There is a single undead archer enemy placed here also, who should attack you from a distance to grab your attention.

It is near points SB 3.2 and SB 3.3 on this image[guides.gamepressure.com].

Very strange, maybe I did my first save before enabling the mod, not sure to be honest, I can see elements of an area beyond that on the map, and I have obviously got epic encounters abilities like tricks of the trade etc, its all very odd.

I just have a bunch of rocks just past a torch where the opening should be, maybe I should try some sort of editor.

Do you have screenshot of where the opening should be? If everything behind it is there, you could teleport behind it and probably be okay.

Print screen is not working, there wasn't a skeleton archer either, I must have goofed up somewhere, I enjoyed the rest of the mod though, dw about it I can't seem to teleport either, seems like something didn't load quite right.
