Can't merge 2 or 3 esp's that require other mods into 1 file

[Dimitrisgb]

I 've been trying to merge a mods that has 2 esp's into one with no succes.

The new .esp that is created lacks a lot of things (objects like stairs, platforms, trees etc, map markers, NPC's). Not only that, but it has a size ofn77,7 MB, even though the 2 esp's that are created have much less than that combined.

I 'm guessing that the main problem is that the mods that are required to play my mods are TWMP related (Tamriel, Valenwood - Elsweyr). When I load my mods, those TWMP mods are loaded as well. So, are they merged as well?

Am I doing something wrong? Missing something?

When I load the two esp's I set them both as active files (don't know if that helps).

Not only that, but I checked one of the mods I made and there appear to be almost two of everything in some places, like buildings, characters and signs.
