Chaospisser

Hi, I just started with my first mod and all worked out quite good. So my problem now is: I made a quest and I want it to stark with a force greet dialogue. When I created the dialogue It was all fine. As soon as I added the force greet package to the npc who is meant so start the conversation and chose a topic from within this quest I wasn't able to use any dialogue from this quest. Even new Branches created within this quest wont work after a force greet topic was once chosen from this quest. When I made a new Quest, which was a exact copy (except of ID and name) and deleted the other one. All dialopgues where available again,until i added the force greet package again. Any Idea what could cause this problem or how to fix it? Thanks in advance for any help
