seems like one of a couple things happened.
(1) some kind of mistake happened in the magical ms cloud and you were “gifted” the plane by the msfs gods.
(2) you bought the plane at some point from the mp for 2020 (and clearly forgot) and it’s appearing in your hangar in 24, like it’s supposed to.
here’s a list of all the planes that come with the game. if you peruse the list you’ll see that the fss tecnam p2012 isn’t included there.
