In my Hardcore world -I don't know, if is that effects it- I built a villager breeder, with all the needed stuff, eunogh beds, made sure, the other grown ups not taking the beds, farmer villager and a regular one, in teory, they need to breed. But the breeding always failing, now for 10 Minecraft days straight -the chunks are loaded-.

Oh yes, and it's the most know, carrot farm automatic design, I checked and watched the tutorial, but everything is at correct place.

If anyone have any experience with that, please comment.                                                                                                                                                                                    

I really apriciate every help!

       Thank you, Good_Game

if you're using eaglercraft there's prob a bug or two effecting villager breeding

if you're using java then you're doing something wrong
