Player - I'd like you to make me a Mammoth Trophy.
Patsy (my taxidermy guy) - OK, I'll have that for you sometime tomorrow. (wait 24 hours and enable mammoth in cavern)
So, could I just put this in his dialog fragment for that to work?
Utility.WaitGameTime(24)MyMammoth.Enable()
I'd try it out myself, but I'm at work, and this idea just popped in my head during the morning commute, lol.
