Fix the bug

I really love the game but there is a glitch at level 58 in which it asks me to sell a goat that I bought and raised. But it doesnt give me the option to sell it. I downloaded the game 3 times and redid all the levels just to see if the bug was fixed, but it wasnt. Can you please have a look at this problem?!
