After making a portrait, I make three copies of it: _h, _l and _s versions (200x200, 100x100 and 50x50 size) and placed them in the portrait folder. But when I open the game, the game does not use the _h version at all. I tested it by deleting the _l and _s versions of the placeholder portrait and it no longer showed up when selecting a portrait. I then left the _l version and it was available.
I then made the _l version of my custom portrait 200x200 sized and it was available for selection.
Is this a bug or was I simply doing something incorrectly.
