multiple turtle bugs

Turtles are still really buggy. For one, the first time I got two turtles to mate, they had the egg in the water and crushed it. Then, one of the turtles just kept running into a wall and wouldn't move on its own. When it does this, it won't except seaweed and if you hit it, it wakes it up from the wall/useless state, but it still won't mate. (They are in a blocked off beach, probably 40 by 40. theres dryland and water they can access. I got another turtle and it mated, but no egg was dropped and after mating it just went into the swimming into the wall state. Please resolve as soon as possible.
