Hi,Love AssetGraph Tool, I bet it will become the most popular and useful AssetBundle Tool in the future.

Recently I find out a issue.
if I Set the Manifest Name(at the node Build Asset Bundles) same to it's parent directory name, then I get a build error,and lost the Manifest bundle at the build result.

The error message:

FileNotFoundException: E:/UnityProjects/SimpleABGTExample/Assets/TestAssetBundlesBuild/TestAssetBundlesBuild does not exist
System.IO.File.Move (System.String sourceFileName, System.String destFileName) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:318)
