Error when loading asset after using PreloadDependencies

Hi, I'm digging around with the addressable system (v0.5.3) and so far I tried the following scenario :

1) Preload everything with a certain label, likely during a loading screen.
2) Load needed resources in the scene as we need. With AssetReferences each calling LoadAsset.

The issue is that when calling LoadAsset, if the asset in question was in the label that we preloaded, I get the following error :

Code (CSharp):

Is this a setup issue? It's possible I'm misreading the intended flow for these functions, but it looked like a god fit.
Otherwise it looks like I'm left with having to maunally load each AssetReferenc during the loading screen?

 

Two things:
1. in the next release we'll have a DownloadDependencies API that should avoid this.
2. Seems like we may have a bug. Were you in Virtual mode? Does it matter if the groups are setup to be local or remote?
