I know I cannot fix this problem, I just want to prevent it. Basically, I am making a quest mod, with dialogue and all, and I will be deep into making the quest, when all of a sudden the dialogue will not load, it will just crash when I click on the ID. This has happen 2 different times, and both times I have just scrapped the quest. I am wanting to try again, but I do not want to waste hours and hours working on it, if it is just going to happen again. Does anyone know how to AVOID this?
