Hi, I'm not sure if this is on purpose or if it's a bug, but the Nether Sporelings can't be tamed for me. Again, not sure if it's on purpose or not, but just wanted to know why I can't tame them. I'd really like to tame them, they're so cute

This is intended. Only the passive Sporelings from the Overworld are tameable. The neutral and hostile nether ones are not.
