Missing Downcast: StateTransitionStageLabel about iyes_loopless HOT 4 OPEN

Please post a copy of what the message looks like, and what your app setup code looks like.

From just your description, I have no idea what is really going on.

from iyes_loopless.

The message is

Missing downcast: StateTransitionStageLabel(TypeId { t: 2123205023094397789 }, "fallen_project::game_states::GameState")
Missing downcast: StateTransitionStageLabel(TypeId { t: 14454845288124870650 }, "fallen_project::game_states::loading::LoadingState")

The states are

#[derive(Component, Debug, Clone, Eq, PartialEq, Hash)]
pub enum LoadingState {
    Idle,
    Loading,
}

and

#[derive(Debug, Clone, Eq, PartialEq, Hash, Deref)]
pub struct GameState(pub String);

They are added via add_loopless_state

app.add_loopless_state(LoadingState::Idle);
app.add_loopless_state(GameState(TITLE_STATE.to_string()));

I think I know where this message is coming from. It seems to belong to bevy_mod_debugdump and is printed right here. Seems like it doesn't know how to handle iyes_loopless's custom stage type.

Basically, it doesn't seem to be an issue with iyes_loopless.

Thanks. I didn't know what the message meant. Hope you guys resolve it on their side.
