Xenobionic patcher is likely able to help with a large number of issues that may-or-may-not occur in these kinds of cases. It does seem to already take into account of things like Nagas, who don't have legs, and Android Tiers, who have their own 'bionic' system instead of the regular fleshy bois.

Kurin are not fully supported, you can't put all tails in the place of their tails (I can confirm that the Manipulator Tail can't be used to replace their tails)
However there is a seemingly abandoned patch for them (that doesn't fix all the tails, if any) https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2460129524&searchtext=kurin+evolved

Hy Acerrrr12 [ENG],

can you give me the link to the exact Kurin mod you are using?
This version works on my side, on the non beta branch at least:

Huh, must have been a different mod interfering, thanks.

Could you make the mod ignore Androids from Android tiers, specifically this version:

Your mod tries to patch some extra balls on the Androids and tells me with red alerts its problematic can't find attach points :)

The Mincho race is a mint chocolate chip slime race and throws an error at start up. I haven't tested them out yet so I don't know what will happen. Is there anything I should look out for? And can I play with them regardless or should I avoid having the Mincho in my game with EvolvedOrgansRedux?
