Exactly. I love that this mod gives a naturalistic light to prehistoric creatures, but by allowing them to destroy blocks such as stonebricks kinda damages this aspect. They're not cannons, they're creatures made of flesh and bones.
I've realised that creatures will only break blocks when their hunger bar goes below 75%, so as long as you keep them well fed they won't break out of their enclosures. But I still think they should add a config to change which blocks they can or can't break.
A config to choice what blocks they can break makes sense, but I feel that them not being able to break stone tier materials should be the default condition. If not it would be like having the scaly dinosaurs variants as the default models.
