Alchemical Familiar - Homunculus ancestry not showing
 

I swear I built an alchemist awhile back and was able to choose the Homunculus as an ancestry (after taking the Alchemical Familiar feat) on the familiar's sheet. Now I don't see that ancestry as an option, am I missing something?

There has not been a homunculus ancestry before. If the familiar looks like an animal, choose the appropriate one, or use the Other option if it's something else.

Ah, I probably filled it in as custom or something. Thanks
