wait no,it wasnt a year it says that last update was 30 oct of 2021 on the more info
If I look at "more info" it says the last update was "6 days ago"
If I look at when the downloadable files were last updated, it says "Nov 02, 2020" which is just over a year ago.
Best guess I can come up with is that the more info update was an update to the game page, not to the game itself. But you have me very curious now that you've pointed me in the direction you'd been looking!
