I've commented out pretty much every other plugin/system add other than these (main just adds this plugin then runs):

        app
            .add_loopless_state(GameState::AssetLoading)
            .add_plugins(DefaultPlugins)
            .add_loading_state(
                LoadingState::new(GameState::AssetLoading)
                    .continue_to_state(GameState::Playing)
                    .with_collection::<LevelBuilderAssets>(),
            )
            .add_enter_system(GameState::Playing, setup_lights)
            .add_enter_system(GameState::Playing, spawn_grid)
            .add_system_set(
                ConditionSet::new()
                    .run_in_state(GameState::Playing)
                    .with_system(hover_and_click)
                    .into(),
            );

I have the stageless feature enabled

bevy = { version = "0.8.1", features = ["dynamic"] }
bevy_asset_loader = { version = "0.12.1", features= ["stageless", "serde"] }
iyes_loopless = { version = "0.8.0"}

I hope I'm missing something obvious.

bevy_asset_loader version 0.12.1 requires iyes_loopless version 0.7. There is no released version yet that supports iyes_loopless 0.8, but the main branch does.

Oh got it, thanks!

EDIT: seems to work well

[NiklasEi]

I just published version 0.13. With that, you can update to iyes_loopless version0.8.

Thanks!
