I play Minecraft Bedrock, v. 1.14.1, noticed this bug after a recent crash bug you fixed not long time ago. Before that, everything was fine. I had two eggs of turtles and I decided to hatch them. I have a handmade beach with yellow sand and water, hatched eggs successfully. I fed them with seagrass, but they do not lay eggs, even though I got XP for it and one of them got pregnant and “bigger”. I also tried to remove walls surrounding it and they never left anywhere, so it cannot be their NOT home beach. i also tried to breed other turtles, went on a real beach in jungles, from where I got very first eggs, I founded local turtles up there and repeated the process. They got pregnant but never started laying eggs as well. Just in case, see my farm I made. I successfully hatched eggs there and it worked before.
