Mobs are getting stuck on underwater items like coral, sea grass, and kelp. Fish, drowned, and sea turtles are all being affected. Picture attached. The 3 fish in the picture will not move and will die if I attempt to break the coral they're stuck on. Drowned get stuck on kelp and tall sea grass and then spin in circles
Swimming mobs getting stuck spinning in circles is tracked at (MCPE-45645). We can track fish getting stuck in coral on this report.
