Sanity down results: problem of model or program?

[no1xsyzy]

For a quick example:

Using 256x256 ver.171125
White twin tail, purple eyes. All off but hats on. style to the right.

That's just an easy condition for sanity down result. Actually, any random-by-human conditions will lead to such result. Also, setting hats option is really bad. That should be reset by default.

My guess is that the problem is the lack of such type of girls in the training data.
Anyway, though the problem really sucks, the project seems good.
