# Objective Fixes #12667. ## Solution - Stored [AssetLoadError](https://docs.rs/bevy/latest/bevy/asset/enum.AssetLoadError.html) inside of [LoadState::Failed](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html) as a Box<AssetLoadError> to avoid bloating the size of all variants of LoadState. - Fixed dependent code ## Migration guide Added [AssetLoadError](https://docs.rs/bevy/latest/bevy/asset/enum.AssetLoadError.html) to [LoadState::Failed](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html) option Removed `Copy`, `Ord` and `PartialOrd` implementations for [LoadState](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html) enum Added `Eq` and `PartialEq` implementations for [MissingAssetSourceError](https://docs.rs/bevy/latest/bevy/asset/io/struct.MissingAssetSourceError.html), [MissingProcessedAssetReaderError](https://docs.rs/bevy/latest/bevy/asset/io/struct.MissingProcessedAssetReaderError.html), [DeserializeMetaError](https://docs.rs/bevy/latest/bevy/asset/enum.DeserializeMetaError.html), [LoadState](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html), [AssetLoadError](https://docs.rs/bevy/latest/bevy/asset/enum.AssetLoadError.html), [MissingAssetLoaderForTypeNameError](https://docs.rs/bevy/latest/bevy/asset/struct.MissingAssetLoaderForTypeNameError.html) and [MissingAssetLoaderForTypeIdError](https://docs.rs/bevy/latest/bevy/asset/struct.MissingAssetLoaderForTypeIdError.html)
