Bukkit

I'm not able to breed horses with this plugin installed. If I R click (with a golden carrot/apple in hand) on an unclaimed horse, I get the error "you must claim this horse to ride it".

After claiming, I R click on a claimed horse with a golden carrot/apple which results in the hearts floating over both horses to show breeding, but no baby appears.

Am I doing something wrong or can this be fixed?

Thanks for the great plugin.
