You know that using a NoCD is very unnecessary in this game, right? A simple 4-byte edit to the Twallanian NoCD works fine.
Any hints on which 4 bytes to modify? Opened one of the Medieval mods with a hex editor, and compared it with the Twallian nocd, couldn't see any obvious changes to be made. But then, I'm not awesome.
(something to do with the .Sims3 namespace string?)
