Incorrect paths for items created in collage pages
When viewing a collage, then navigating to a subfolder. The path to the subfolder is modified to include the collage row + column that was navigated through. This is a problem when adding new content, since it will be recorded as being located within the path including the collage row,column rather than within the actual folder.
Perhaps this issues is realted to how items are added to the collage page? See what happens when adding content to an existing item that is referenced by collage.
