Ratings do not change. Answered
So I decided to give the knex pinwheel here: https://www.instructables.com/id/Knex-Pinwheel/ 4.5 stars out of 5. However, the rating did not change.
Before I rated it it was at a 3.38, with 3 ratings. After, it was still a 3.38, with 3 ratings. I tried rating it other ratings and this did not change the rating either.
Again, this shouldn't be on the top of a priority list or anything, but its definitely worth fixing.
