I'm pretty sure I saw another thread with this same question awhile ago but I can't find it. So, I was wondering, can you inbreed on HP? On Horseland, you have to be careful because you can accidentally do that if you get your lines mixed up but I thought that other thread said that the system here on HP won't allow it?

Yup. You can't inbreed. I believe it may kind of "lose track" after so many generations and stop giving you an error, but it will not let you inbreed for at least the first page of the pedigree.

Okay, thank you. Just wanted to make sure!

In a way you have to be careful as the system will only stop you if the line breeding is within the pedigrees of the 2 animals you're trying to breed. If you can't see it on the "view pedigree" page the safety net won't catch it either.
