SteamInventory.GetDefinitionsWithPricesAsync() never returns from await call

[williamdewaynecorrin]

Hello there! Thanks to whoever ends up reading this. I'll be as concise as possible.

When calling:

InventoryDef[] storeitems = await SteamInventory.GetDefinitionsWithPricesAsync();

Inside of my async void Start() MonoBehaviour function - it never returns. It appears to be spinning forever in the await call.

I know its not just on my end, because I can get SteamInventory.Definitions from a normal SteamInventory.LoadItemDefinitions(); call.
And, I am loading everything else fine as well, including asyncly - for instance, the following also works just fine:

InventoryResult? result = await SteamInventory.GetAllItemsAsync();
if(result.HasValue)
{
    Debug.LogFormat("Local Steam user has purchased {0} items for this game.", result.Value.ItemCount);
}

I am able to extract all my item data out of the SteamInventory.Definitions, and also get the local client's items from SteamInventory.Items. Everything is populated just fine, except for the price data - which is always set to 0.00 - hence why I even switched to calling GetDefinitionsWithPricesAsync() in the first place.

I would expect either a null array, empty array, or an array of InventoryDef - so I presume this isn't the correct behavior.

Running on Windows 10
Unity 6 (6000.0.42f1)

Hopefully I didn't miss something easy here, and ended up bothering you for no reason.
Thanks again!
