(WARNING: SPOILERS!)

The problem is following: I made a mod that alters the Thieves Guild's quests that involve becoming Nightingales and going after Mercer in such a way to make it possible to refuse transacting the Oath and skip the Oath and returning the Key to the Sepulcher altogether.

The mod can be found here: http://skyrim.nexusmods.com/mods/18685

However, according to the numerous reports, my changes don't seem to work for many people - from what I managed to understand, the dialogue I added fails to update the quest stages. I have previously read some information that one of the recent patches broke the game and caused mods that alter vanilla dialogue to not work properly. This seems to be further confirmed by the fact that for me, the mod works perfectly fine on an unpatched Skyrim.

The question is: is there a solution to this problem, and if yes, then what can I do to finally fix this problem? I find it really annoying to know that a mod I made does not work for others and I don't even know why.

Maybe it collides with some other mods, tell 'em to try without additional mods running in the background.

If your mod is start game enabled, try changing that. Create a new start-game-enabled quest that does nothing but start your quest-that-has-dialogue.

@Ingenue: Do you mean "start game enabled" for the entire mod or for the quest? In the first case, I don't know if I ever saw such an option, and as for the second one, my mod does not create any new quests but instead modifies a vanilla one (three quests, to be exact), so I don't know if it would be of any help.

1. There is what is referred to as the Dialogue-Bug: http://www.gamesas.com/topic/1403919-dialogue-no-longer-works-thread-2-quest-bug-dialogue-scenes-etc/ - we are almost at the end of our second topic on it! - which may impact both mod-created and vanilla quests.

2. Saved-Game-Compatible: In many cases, altering quests (vanilla or modded) will appear not to work because the original quest "data" is saved inside the saved-game. There is nothing you can do to fix this ... Only starting a new game would enable such changes to appear for everyone (note: probably, there are some involved tricks that can make it appear to work for everyone ... oft termed Piggy-Backing on Vanilla Quests ... but often such tricks aren't applicable to a specific situation)


Given your description of "many people", I suspect your problem is No2, not No1
