Fruit disappears sometimes Snake in C - c

Question

Im making a snake game in c, most things seem to be working right but I found a bug that I can't seem to fix. The fruit in my game sometimes just disappears for no reason. First, I thought that the problem was that I was generating it outside of the play-area but I put a restriction on that and the problem still exists.
