just trash the contract and sell the resist to a PC. You'll get better moolah for it that way anyway.
It was probably removed because no one (or very few people) were using it as the demand for enchantments and resistances is high enough that most of the product can be sold to PCs.
The craft that needs a contract dealie like this is lesser jewelry making. Back when I was making copper rings and amulets I made soooo many for practice and trying to make exceptional elemental ones. I ended up with like three or four boxes of assorted copper rings... and while I acctually sold quite a few to PCs, I eventually sold several boxes full of rings to the pawn.
