I'm getting an error with a boiler plate project for bevy 0.9.1 ```rust
use bevy::prelude::*;

fn main() {
App::new().run();
}

error[E0774]: derive may only be applied to structs, enums and unions
--> C:\Users\jacob.cargo\registry\src\github.com-1ecc6299db9ec823\bevy_render-0.9.1\src\extract_resource.rs:15:1

15 | #[derive(Resource)]
| ^^^^^^^^^^^^^^^^^^^ not applicable here

20 | | fn extract_resource(source: &Self::Source) -> Self;

#

rust is up to date, this is just strange

#

same with bevy 0.9.0

#

cleaning and compiling other 0.9.1 projects is fine

#

looking at the file in github, it doesn't have the #[derive(Resource)] line
https://github.com/bevyengine/bevy/blob/main/crates/bevy_render/src/extract_resource.rs#L16
looking through the history it doesn't seem to have that line in any commit (it only has a few changes made)

#

what happens if you just go into file and delete that derive there?
