Re: Couple FFC Questions...
I can't answer the second question (though I can question why this is in the normal ZQuest Editor Help subforum ;)), but for the first, I'm almost positive they do continue to animate. I recall hearing a method for making time work on the entire overworld by putting the same FFC, which animated/cycled, on every screen on the overworld, and then when it hit 0, no matter what screen you were in, it'd direct warp you to a new version of the overworld (night, for example) where things were changed. So, yeah. That's what leads me to believe they do constantly animate (because if they didn't, the timers would reset every time you went into a new screen).
Re: Couple FFC Questions...
I believe they constantly animate as long as you've set its carryover property.
