Skyrim crashes when i select custom dialogue

[Kellet9009]

So yesterday i decided to add some custom dialogue using vanilla assets to a follower i made, and it worked flawlessly, but suddendly, today, when i decided to add more, this happened:

 

First i added it, and tested it in-game without generating the .lip files, and it worked, then i opened CK again, and generated the .lip files for the new lines.

 

But now, whenever i select the new dialogue options, the game instantly crashes, while the dialogue i added the first time works perfectly.

 

I have no idea what is causing it, i need some help with it ASAP, i'm losing it.
