the ai with spawning tropical fish in a  bucket seems to be glitched. I build a fairly large pond (80 x 80 blocks) and spawned several tropical fish in it with the bucket item and the fish seem to glitch out and bunch up the corners of the pond, leaving the rest of it total baron. it's almost like they are being drawn to something in the corners but there is nothing there. I even tried to push them away from it but they justs swim right back.

I tried remaking the pond 3 different times and without fail this bug will occur every time.
