Steam won't start TW3 modded with NMM

[shiki00]

I installed several mods using NMM, and merged all conflicted files using script merger. The game runs fine (all mods working in fact) if I launched the game from NMM, but if I start it from Steam, the game would crash.

 

I've done the following :

 

- merge all conflicted scripts

- create a custom mod load order file in Documents folder

- applied the Unification patch

 

But nothing works. The game runs fine if I launched it directly from the directory or NMM. Only crashed when I launched it with steam.

 

I'm sorry if this was answered before, so any links to the previous threads would be appreciated. A simple search yielded bunch of several unanswered threads.
