Hello. I have some problem.

I made Quest (with Scene), wich begins by Actor Dialogue Event. I put it in SM Even Node.

But NPC didn't talk together, when I checked my Mod in the game. I checked the quest through SQV and I saw that my Quest has began, but Actor 1 didn't go to Actor 2 and didn't talk with him. And all time my Quest wasn't reset so NPC weren't talking together

assuming your http://www.creationkit.com/index.php?title=Category:Scenes (dialogue parts, packages, phase ending conditions etc), are you sure it's actually running?

you'll need to start it either by script or set it to "start with quest"

also, check the scene's actor data and all that stuff and make sure no actors that might not be present are set to non-optional,

also chech if the scene is set to end or pause when the actors are in dialoge, it'd end right when it starts then.
