Prior to V3, some of the silk products were made wrong...or at least, made in an inconsistent manner which wasn't noticed until everything went in and the recipes were added to the database. In order to make them work, I fudged the database. Those items are now fixed, but the database needs to be updated. I kind of used Dark Silk as my test item because I simply ran out of time this last go-around to fix everything up properly.
There may be a few others. I have an easy way of telling which are going to be problematic, so hopefully soon (possibly tonight), I'll get the database fixed up all proper like.
