I just pick up BE few days ago. Crafted my own pet and when I try to tame it, it said my data storage has too many pets and ask me to make room meaning geting rid of it I guess. But My datapad storage has no pets except my 3 At-Sts and protocal driod. I need to know if this is a bug or they made it like this, so my faction pets counts as my reg pets ?
