Legendary Familiar Gone due to Update

I need to know which Legendary Familiar was removed from Storage, if this has happened to anyone else. My beasts are sorted by grade. And there was a gap where a Familiar should be, but i cannot remember which 1. Happened to both my Beserker and Assassin. I know my beserker had 12 as well and now there only is 11. She now has 2 storage spaces left when she should only have 1. Please if anyone can help me, much appreciated.
Thankyou.
