I have a multilingual Umbraco website with a Culture set against each language tree in the typical way. I’ve noticed that when the Language isn’t English (e.g. “mi-NZ") that the following code returns no results:

var mediaFolderId = 3921;
var folder = UmbracoContext.Current.MediaCache.GetById(mediaFolderId);
var children = folder.Children;

This returns a full list of children when executed on a template in the context of the English tree, but nothing in the other tree.

Is this a known issue? this is on Umbraco 7.4.3

thanks
