[BUG] I think I found a bug?

Question

It isn't all that horrible, but when you complete 3 lessons in a course (it has happened to me in HTML CSS and JS), a pop up on the side of the screen says you get the Hat Trick achievement. I checked to see if I really got it each time it happened and it said I have yet to earn it. Makes sense though, since you need to complete 3 courses to get it.

Long story short:

You get a fake Hat Trick achievement when you complete three lessons in one course.
