Im on the xbox one x on the latest version with all the dlc. I almost always use the synthetic evolution ascension perk and never had a problem until this last playthrough which i started after the latest hotfix. After i modded my species to become fully synthetic i could no longer change my species living standard. It stays on transubstantiation synthesis which i believe is only for when that species is getting assimilated. But i tried to change it to social welfare and i did "change" in the fact that it made me wait 10 years to change it again. But it stayed on transubstantiation synthesis so i waited the 10 years and it did the same thing. I took this screenshot after the 2nd time i tried to change it.
