I've got to admit I'm not too fussed over this. You can Always use the console to give those models to yourself.
It isn't an actual, troublesome bug, is it?
In any case, I really don't know why it wouldn't work. Though.... Did you get any costumes show up without descriptions?
It might be one of those. If RESOURCE\INI\TEXTS\ENGLISH\models_description.txt does not match up properly, the actual description would be missing in the game.
There are indeed costumes without descriptions and some of them apprears but not all of them, I don't know what the problem is, maybe a little bug indeed?
How can I do that? Use the console to give those models to myself?
It's not troublesome no, as some people said earlier I'm maybe the only one here who wants to collect all costumes LOL
