Xenogerm Implant Bug?
I may have saw this brought up a few times, or something along the lines of it, but I am putting this out there. There is this issue when I create a custom xenotype with the Implant Genes ability, it doesn't work right. Specifically, if I set the xenotype with traits are inheritable, nothing happens other than the pawn falls into a coma and they 'regrow genes' even tho they don't gain the implant ability themselves or any other genes for that matter. If I don't set genes to inheritable, baseliner pawns I try to implant won't work in the first place, saying 'pawn is already baseliner'. Interestingly, if I do it to a non-baseliner xenotype, I can implant, but the results are like the first issue, having no genes received from the implant. I've tried this with both modded and unmodded xenotypes. The only xenotype that implants correctly is the preset sanguophage.

Implant is only for xenogenes, never for endogenes. But the rest of what you're describing are bugs for sure.

Ah. If I may ask, what is the key difference between xenogenes and endogenes specifically?
Bathory Dec 27, 2022 @ 3:26pm 
Sure. Endogenes are inherited, while xenogenes aren't. So for example sanguophages can use implant to pass on their xenogenes, but not their endogenes(assuming they were a pigskin or something before becoming a sanguophage).

I've noticed that if the pawn with an inherited implant gene and no xenogenes uses the implant ability on another pawn, everything still works- but of course, no genes are passed on because the implanting pawn didn't have xenogenes. I think this is more of an oversight than an outright bug- still technically a bug I suppose.

So if I understand correctly, endogenes are supposed to be more cosmetic and/or physical genes? Like Yttikin fur or Imp horns?

They often are. But really any gene can be an endogene. Though technically not all endogenes can be inherited by offspring, i.e. archite genes.

Pigskins, dirtmoles, impids, baseliners, and yttakin have endogenes. As in, inheritable genes.

Sanguophage, hussar, highmate, and genies have xenogenes, as in non-inheritable - but of course they usually have endogenes too, such as melanin and their birth xenotype's endogenes.

That clears it up I suppose, and I thank you for the info.

I'm having the same issue with implanted xenogenes not transferring from a custom xenotype with "inheritable" checked. My theory is that all of their genes are considered endogenes when this box is checked making gene implantation do nothing.
