In my minecraft worlds, I have some fish tanks that contain 1 or more dolphins. I have spawned them in creative.
The problem is that they are always swimming into one block and suffocating. If I make them invulnerable using /summon, they dont suffocate but they will still continuously swim into a specific block (Which is never a glass block).
Thank you for your report!
