just an "out of curiosity" suggestion, have you tried building an island made of sand in area that pregnant turtle swims in circles around? only asking because I experienced a similar issue, but my pregnant turtle went more than 3000 blocks (euclidean) away from location she was originally hatched, to lay eggs. Then, when she got there, she just circled until I replaced dirt with sand, and she laid eggs. I followed her for hours, and server owner followed most of the trip. I reported mine with all details as MC-173041, in case GoldenHelmet would like more details from mine. one difference in mine and all that I have seen listed here is that these all seem to be bedrock edition, and mine is Java edition 1.15.2
