[LE] Make the dialogue run only once

I am having troubles trying to make the dialogue run only once in the entire playthrough.

Instead of a reset timer, a line can be set to run only once in the entire playthrough.

I am working on a quest whith Player and NPC are introducing themselves to each other.

There's no quest stages so far, just a few lines. The whole dialogue is supposed to happen only once.

Here's the dialogue, initiated by Player (I am reducing the lines to simple lines for showcase purpose):

1. What's your name?

1.1. I'm Jack. And you?

1.1.1. And I am Jane.

1.1.1.1. Nice to meet you.

 

These are two topics (1. and 1.1.1.) and two responses (1.1. and 1.1.1.1.) I flagged the responses to "Say once". The problem is the first topic prompt pops up every time I load the game. That means I am having that line among dialogue options when I enter the conversation with this particular NPC, and I have a "brilliant" opportunity to ask her what's here name like I am an idiot.

What can I do in this situation. I can't flag the topic to "Run once", can I? Do I have to organize the quest stages? I've implemented this tiny  bit of "Introduction" dialogue inside the bigger Quest where all the lines for this NPC are. I don't want to mess around with new quest stages for that Quest. Why does the flag "Say once" not do its work! It looks like it only prevents the dialogue from happening during one game session (sitting). As soon as I exit the game and load it up again, the dialogue is there...

you need to register it to quest setage  so only on that quest stage will it play. use the conditions to choose your quest and set the stage required for the dialogue so when your quest advances the dialogue no longer shows up unless the quest stage resets to the stage in the conditions

Okay, I guess so. Thanks!
