Why do the Pajamas work differently for Sim Children?
(This does not apply to all expansions) They use the old 30 record format for skins even though they have the additional 3 records in the files. The old format requires a certain file naming convention be used for the pajama skins to show up. They are also based around the body used and not the character. Trying to assign pajamas to the character itself results in a character that just wears whatever happens to be on at the time as pajamas.
