I think I may have fumbled my phone and accidentally released one of the wolves I was planning to breed, and to say I am mad at myself is an understatement.
I'll take it as a hard lesson to be more careful, but I wish I could lock my wolves as an extra precaution to prevent the release button from showing up on the wolf's page, kind of like how the button temporarily disappears while a wolf is on the flea market. It could perhaps be changed in the den's settings, or maybe in the player's settings.
It's a small change, but I think it could help prevent some future accidents. I would be really grateful for this feature!
