This was PA 1.4.2, Mafia r7939. It's working correctly today though (using Mafia r7940). I was on a pretty terrible internet connection yesterday, so that may have been messing things up. I'll let you know if I see it again.
Found something odd today:
This looks odd; there's no mall price listed, and we have this mystery line about 994, which is the item# for tiny plastic Susie.
I've been working on this script a bit recently; I have Crimbo '09 monsters mostly working, and last night I added preliminary support for Stealth Mistletoe. I'll try and get it presentable so I can share it with everyone.
EDIT: Or not. Vacation time is over and I haven't made much progress...
