# Objective
- `asset_server.watch_for_changes().unwrap()` only watches changes for assets loaded **_after_** that call.
- Technically, the `hot_asset_reloading` example is racey as the watch on the asset path is set up in an async task scheduled from the asset `load()`, but the filesystem watcher is only constructed in a call that comes **_after_** the call to `load()`.
## Solution
- It feels safest to allow enabling watching the filesystem for changes on the asset server from the point of its construction. Therefore, adding such an option to `AssetServerSettings` seemed to be the correct solution.
- Fix `hot_asset_reloading` by inserting the `AssetServerSettings` resource with `watch_for_changes: true` instead of calling `asset_server.watch_for_changes().unwrap()`.
- Document the shortcomings of `.watch_for_changes()`
