Asset Store package called "AssetBundle Manager & Example Scenes" has a script called "AssetBundleManager" which is missing line "assetBundleName = RemapVariantName(assetBundleName);" in the start of AssetBundleManager.UnloadAssetBundle() function.

Reproduction steps:
1. Open project "Repro.zip"
2. Open scene "TestScene"
3. Make sure that Assets->AssetBundles->"Simulation Mode" is disabled
4. Play
5. Notice the console output (Especially last two lines)
6. Open the "AssetBundleManager" script and uncomment line 356
7. Play and notice the console output again

Workaround: Adding line "assetBundleName = RemapVariantName(assetBundleName);" in the start of AssetBundleManager.UnloadAssetBundle() function fixes the problem.
