This game got a new Patreon i.e. myself.
In the current public build(0.6441 Alpha) I'm trying to catch Foxen male(The non furry one) and I haven't seen any.
Also, which kind of "lure" do you use to catch male Harpies? I've tried with everything, both milk and sperm but neither of them seems to be of any interest.
---Edit---
I've spent about 1 hour to try to breed a Foxen male(non furry) but now I've given up.
However the Harpy male could be bred.
And about the Harpy male, I found the thread:
You must be registered to see the links
And it says there's no such thing to tame male harpies...
I think it's confusing that there are more than 1 item for some of the races :/
