So, as I walk through towns and such, I randomly get the dialogue window for NPC's that I did not activate. Sometimes the NPC's is so far out of range, I couldn't have activated them if I wanted to.

Usually I get "..." or "..." followed by the default greeting text. Other times its the default greeting text. It happens with Vanilla NPC's and those added by mods, such as MCA.

I know EcoAdjMerchantSkills is what's producing the "..." (as it's running a script during it), but I'm stumped as to what's bringing up dialog windows. Do you have anything in your warnings.txt?

EDIT: I fixed it. I had two versions of the disposition mod running [one by economy mod, and one including BTB edits.] That seems to have removed the random dialogue.

I have quite a lot in my warnings.txt Most of it is about not finding a leveled creature. Anyways, here you go:

It seems to happen when ever an NPC acknowledges me. But not every time.
