Turtles sometimes "glitch out" and can't place eggs

I was exploring the world in search for a jungle (because i needed the jungle wood all of the sudden)
Then i stumbled upon a small beach and saw two turtles!
I had just looted a hidden treasure, so i had iron on me, and i've also taken a silk-touch pickaxe in case i see some coral reefs

I decided to make shears, collect some seaweed and breed the turtles, so i can get some turtle eggs.
The first couple of tries have worked, then on the third try, the turtle couldn't decide where to place the egg, so i flattened the area for it.
The turtle then started digging up the sand ENDLESSLY with a lot of particles summoning in, but the egg was never placed.
i decided to record it bug and send it here

ALSO: when i had breed the turtles, only one of them required seaweed
they both did the first time, but anytime i had breed them afterwards, only ONE of the turtles required seaweed for them to breed
