In edit package available on Vavoom downloads page there is a msitake in WadAuthor's wcf's. Celing_Waggle line special is declared as Floor group (5), not Ceiling one (3). Also, I believe these wcf's are written somehow bad, because WadAuthor cannot read them, until I copied their contents to new files. Maybe that is because they have large spaces between lines, but I am not sure at all.

I have already fixed them some time ago, I'll send them to Janis so he can update the current ones.

Yeah, I forgot to change group. I checked editing package and found that WadAuthor config files have really bad line engings.
