So I did some digging, it looks like it is Character Body Overhaul that is broken, there is a hot fix if you edit the following
in mod\char_body_overhaul\gfx\portraits\portrait_modifiers\sex_animation_portrait_modifiers
In this folder delete this line of code
normal_cunnilingus_height_correction = {
dna_modifiers = {
morph = {
mode = modify_multiply
gene = gene_height
value = 1.0
template = normal_cunnilingus_height_correction
}
}
}
dwarf_cunnilingus_height_correction = {
dna_modifiers = {
morph = {
mode = modify_multiply
gene = gene_height
value = 1.0
template = dwarf_cunnilingus_height_correction
}
}
}
giant_cunnilingus_height_correction = {
dna_modifiers = {
morph = {
mode = modify_multiply
gene = gene_height
value = 1.0
template = giant_cunnilingus_height_correction
}
}
}
Should enable start-up if that is a problem, carnalities seems stable to launch the game, ill do further testing to see if I can break it or not but that is the fix to crash on startup. It will break carnal courts and animations but it should start up.
