Missing Portraits

[Woodenplank]

None of the units in my map have visible portraits; they're all just blank, dark spots (clicking them doesn't work either).

Has anyone tried this before? Could I have downloaded a .blp to a bad path? Can a trigger function do it? Is everyone as clueless as me? (without providing extra information).

I have a buckload of triggers in my map, so I'm looking for any general functions or imports, paths, etc. that might've done this.

I've also used Optimizer and Widgetizer in the past, could I've messed with it there?

The map is playable and doesn't crash; but portraits simply do not work.

These custom models or standard? Not all custom models define a portrait which leads to weird behavior.

If it's happening to regular wc3 models I have no idea though.

Yelp.

But that's just it; it's all models in the map. From Footmen to Imported stuff.

And it's only that particular map, right?
Also: don't you have earlier map versions to load up and test?
