Okay, so I have this quest that is supposed to run on an event, and not be running otherwise. I couldn't get it to run, so finally I just did a GetQuestRunning (handy command) on my quest, and guess what? It was already running, which is why I couldn't initiate it. I'm wondering if this is just due to my using a save where the quest was not initially an SM event thing, and then edited the mod to make the quest start conditionally upon levelling up.
Was that the problem?
EDIT: Oh and another thing, is it possible to make a quest property for text replacement? It seems like I can only do aliases, and I need a string.
Try loading into a cell from the main menu rather than loading your save. When I test mods, I COC from the menu into a separate cell, then once the game loads, I COC into the cell where my mod is. This prevents any sort of problems from occuring with regards to dirty saves and mods not loading correctly. Also, remember that you're save will become dirty if you load the save directly into the cell where you have a mod, especially if it changes a vanilla component of the game.
