Hello 
im new to Gdevelop and i try to make some little Features for a small RPG Game. Of course the Dialogue-System is very important, so i watched some Youtube-Videos and found a good one i understood the logic and build it 1-by-1. It works good, but when i try to end the Dialogue the second branch of the yarn-dialogue repeats over and over.
In this Dialogue i had some line of text and two options to chose. The text after the options follows the yarn great. But the first branch ends and the second one starts right at the same (or next) frame and this one repeats itself.
In the Video after the first branch there had to be a new collision to get to the next part of the text which the NPC should repeat every time i talk to again.
Here is the code, maybe some experienced Coder will see the problem 
in my cheap solution i changed the variable of DialogueState to 2, so the Conversation ends, but the NPC is quiet.
