Why is the board not showing?

You can see I posted a comment there where I posted the board. However it is just showing a blank space. When I quote it, I can see the board again. Why is it happening?

just how it work :v

Try deleting and posting the board diagram again. I have seen it fail and then work properly on a second try. 

Sometimes just editing your post a little will get it to fully post.

it's not a glitch. it's on regular, too.
