I have never had an offer from the AI to breed with one of my stud horses. I have the stud facility and I lowered their suggested price to half. I have 3 multiple Grade 1 winners and never have received an offer. So my conclusion is that either there is something wrong with the game or I a missing a step. Is there something else that is needed besides setting a stud fee and waiting for an email to come in?

Something is messed up with stud requests. I have been setting my stud fees to 1,000 as soon as they hit the shed. I get requests here and there. Maybe 5 to 10 at the most.

I only know if you breed G1 horses from your studs especially classics like the Derby, Ledger etc. the offers roll in, sometimes unexpectedly. Otherwise yeah it's barren unless the price is reduced to a silly amount.
