Okay I'm actually mad

This game has been driving me crazy, but whatever no big deal. But this actually made me mad, if we are already giving you money, do not ask for more for it to be fertile. I didn't know this was a thing because I rarely buy robux on here, thought it might be okay thus once but no way. Didn't horses worth robux always used to be fertile? I'm so frustrated I'm ready to be done with this game after cybreds. They were almost a good breed and then they got soooo greedy about it
