Hey guys, as Wes cleverly surmised, it was actually a bug fix rather than a bug
And it wasn’t actually a bug fix either! We were counting the cost of the file when it was first set – but with our new Reviewers they’d often go back and make changes 5-10 minutes later on some files… So people were adding up their portfolios and seeing there was a discrepancy, even though the Competition details mentioned this.
Despite that, we were getting a lot of people writing in saying it was wrong (even though it technically wasn’t), especially after our site-wide file price increases, so we decided for better or worse to make it count the current price of files.
So that’s the really long explanation
