[SBP BUG]Build Cache may miss same time

I had find that it will take a long time to rebuild assetbundle when use sbp,althought i didn't change any asset.At last,I find the a few asset will get diffierent value by call AssetDatabase.GetAssetDependencyHash() when restart unity,but if i restart unity again,the hash value may change back.Ps,The asset is the file with suffix ".compute" witch may include same files with .hlgl
