I've tried to load assets via AssetReferences. This works fine in the editor but it fails in builds throwing an InvalidKeyException. I checked whether the references may be at fault, but they appear to use the same runtime keys that work in the editor. So, to me it seems that the assets are not properly included in the build. However, I'm not sure how I could further debug in that direction - the only idea I had was to check whether the build contains a corresponding bundle file. This appears to be the case and now I've run out of ideas on how to further debug - any pointers?
