I on my 3rd attempt in creating a mod as each time I'm hitting on a bug that renders the plugin useless. Half way through creating it, the dialogue stops working when I check it in the game. Each stage of completion I check to see if it works like the others before it. Each stage is the same except for different locations, NPC's & creatures. The first two locations, worked fine. Dialogue appeared as expected and the scripts (all identicle with the same properties for each one) ran perfectly. Then, as before, I worked on the 3rd location (Windhelm) and suddenly the dialogue stops working in every location. The placed creatures are still in the game, so the mod has loaded.

All I'm doing is adding a NPC creature near to the major cities. Have a stables worker NPC sell them through dialogue to the player using conditions that reference a alias I created for them. Everything is basically the same as the vanilla "stable" quest, except for for the creatures. Even if I made an error with the last location, it should not affect the others. There was no crashing when saving (which can wreck a plugin). The only odd thing is that Windhelm had a repeatable error when loading the cell into the CK, but I can't see how it would affect my plugin:


Probably nothing that can affect my plugin as far as I can tell.

So has anyone else hit upon this bug that causes a plugin to stop working for no apparent reason?
