that would be Bridget and Micheal, found in the Heavy file, you can remove the whole preset and Quests file from vin_Base and the Default, Bridget and Micheal take priority, and Characters used to have two files of the Skeleton Base but it is now just one, when the skeleton had two files, before 4.0 it would reconize customs, now it does not, so far anything you do to those two files,Micheal and Bridget, located, in LifePlay, Content, Heavy, Daz, will have the game not work at all, it wont even start, as stated the way if you want customs in the game is to put the name of yur custom with a _M or _F at the end and add them to pop and pop1, in meet random in vin_ Base, where it says generatePersonTemperary(customname_M),or _F, works for me, and the meet couple any scene with generatePersonTemperary canhave its own body preference to it, i run my own presets, and none of the ones that come with the game, i have myown custom presets and quest characters, that i have been useing for two years now and with no problems at all with generating different types of bodies in the game,
