What's the issue? Please include any error messages you receive and as much detail as possible.
I mut replaced my queen/king with a Generation 3 Piebald(Mottled) exactly 2 months ago - the dates are in her bio. ALL spaces after her grandpa 'Shedua Pie' were Unknown, including her great grandmother (Shedua Pie's mom). I clicked on my Heritage yesterday and saw that my queen had a whole new line of heritage, where Shedua Pie's mom is showing up, along with an extremely long and inbred heritage. I'm confused on how that happened? And is it fixable? I always assumed Shedua Pie was a 1st generation, and my queen's father Aukai was 2nd.

when I mut repped 2 months ago, the piebald cub I used was a G3 and has always been a G3 until yesterday - it's the same queen, except there suddenly is a lioness named 'piepie' in her heritage that has 4+ instances of inbreeding and I couldn't figure out why :( I haven't mut repped again - I haven't made any changes at all.

I snooped around a little and saw that Shedua Pie retired yesterday (oct 16). Could his retirement mean a lioness in HIS heritage just appeared (piepie)? Piepie was never there, making my queen a Clean G3, but today she just appears - the day Shedua Pie retired. Now my queen is suddenly dirty after 2 full months of being g3 :( is there a way to erase Piepie? She was already removed (meaning she was never in my queen's heritage) and does not exist when you click on her in the heritage page.
