u.u Look I don't know how much more in-depth I can explain this. The moment the Crustle comes out of it's nest, it won't react with any of the spores I'm currently holding. Instead it freezes in place. I does not turn into a brick or whatever, it just freezes in place without moving.
Typically they react instantly when you're holding sleep spore. But now they don't. If I'm not holding any spores, they're supposed to attack you. But now they don't. I'm starting to think they're bugged.
