Categories disappear? – Color By Number! Pixel Art Review

I really like this app, but I have been coloring a lot in the “fish” category, and when I went to look for another today, the entire category was gone. I was working my way through them. I feel as if once a picture is available to color, it should not be taken away. Also, my biggest problem with this coloring app over others is once you have the correct color in a square, it isn’t permanent. I am sick of accidentally hitting an already colored square and having to go back and fix it.
