I regret to inform everybody that my quests are all dead. So are the tilesets. Everything has kicked the bucket. Of course, I have a very good explanation for this. You see, I, um, sort of accidentally deleted the folder which contained the ZC subfolder. Oops. So, LotW is gone, which is irritating, because I only had the last dungeon to finish. I'm not starting it again, either, after how long it took me the first time.
Invasion is probably going to be restarted, because I love the idea so much. Unfortunately, I am now back to square one, which I find highly annoying, because I put a lot of work into those graphics, dammit!
Anyway, the moral of this story is: Sorry to anyone looking forward to either of these (that's about 2 people, at last count ), and back up your hard drive frequently, unless you're in need of a good 'ol karmic ass kicking.
