Build Assetbundle出錯：An asset is marked as dont save, but is included in the build

前天Build Assetbundle的時候出錯了，導致打包失敗，具體日志內容如下：

An asset is marked as dont save, but is included in the build:
Asset: 'Assets/Resources/Characters/NPC/NPC_1010.prefab'
Included from scene: 'Assets/Scenes/InitScene.unity'
UnityEditor.BuildPipeline:BuildAssetBundle(Object, Object[], String, BuildAssetBundleOptions, BuildTarget)

 

Building - Failed to write file: CAB-NPC_1010.prefab
UnityEditor.BuildPipeline:BuildAssetBundle(Object, Object[], String, BuildAssetBundleOptions, BuildTarget)

問了技術支持后說prefab沒保存好，那就應該是美術同學沒有保存好就提交SVN導致，我叫美術同學重新弄一下保存好再提交就好了。
