Thank's to my wonderful girlfriend, I have managed to get my hands on the relevant data for the 1.19 patch. As Baxim still hasn't updated CORE I have been unable to patch.
As suspected, EA changed nothing XML wise that I can see. Or at least, nothing that I have modded. So all Mod's are OLS compatible apart from Family Day Out (production suspended) and Simcredible Toilets (will not work for LN toilets, all other toilets will work fine.)
