yea sorry didnt see that i searched dolphins and didnt see a bug on it. so its affecting fish also and also I can stand in my room for 20 to 30 mins and all dolphins will usually die by then. think they are suffercating in the blocks.
it happens when I leave the room and come back all i can really record would be the dead fish left in room from the puffer dieing. Im thinking it is like the issue with villagers where when they unload sometimes they reload on wrong side of fence I think they are reloading where the glass is or on outside.
i have the video where i put 6 dolphins in and left for 20 mins came back they were gone where i send it
