Sounds like what you will need is at the very least a quest script attached to the quest, or an object script attached to something in the area. You can use the function http://geck.gamesas.com/index.php/Special_Variables to make delays like you seem to want. Basically in your script set a float variable to GameDaysPassed then use that to track the days like so...
The above will enable the first reference 24 hours after the quest hits the desired stage, then the second reference 24 hours later. You can just keep going with this for as many days as you have references for.
Thank you David and b3w4r3!
b3w4r3, that looks almost exactly like what I need with one little exception. In stead of each reference enabling after one certain stage (stage 100 the way you have it), I need each reference enabled after each of their corresponding stages in my quest. In other words stage 30 enables my first ref 24 hours later. stage 50 enables my second ref 24 hours later, stage 75 my third ref and so on. I can mostly see how what is there is doing what it does for the most part, but just don't see how to make each stage independent of one another as opposed to enabling after stage 100 in your example. There is a separate mission for each stage, and the player could complete stage 30, take a break from my quest and do other stuff for a couple of game weeks even, and then start my quest back up. But the other ref's would already be enabled if I'm reading this correctly?
Thank you very much, as this is VERY close I think!
