I'm having trouble adding the mod Improved to Operators heavy chest piece which CTDs and I get this log. After I first crash 2X, I dumped the Operators heavy chest piece I had in a container then use a command to add the same amount of Operators heavy chest piece then it crashed (attempting to add Improved); the attached log is from that 3rd try.

Can someone help me figure out the issue and possibly help me in getting an Improved Operators heavy chest? I guess I could just spawn a bunch of operators until I get one, but I'd rather not gain XP from that.
