breeding of turtles is failing

There is a bug in the beta test of update 1.14.60.5 where the following problem occurs, after feeding the turtles with "Seagrass" the turtles should start breeding in the sand to drop the EGGS, but even feeding them several times, on beaches different and expecting a lot I noticed that nothing happens.

In short it is a BUG where the breeding of turtles is failing !!
