Resolution Note:
Unloading an asset bundle that serves as a dependency for other asset bundles still in use can lead to undefined behavior. This includes serialization errors that may occur even if the dependency asset bundle is later reloaded. To avoid such issues, ensure that an asset bundle and all asset bundles that depend on it are unloaded together.
we are updating api docs and manual to clarify the usage.
