texture missing for academy_construction

Missing texture for the scaffold/ladder on the academy construction model

It's not missing from the original https://github.com/zetaglest/elves-testing/blob/479095715c3aa527281419bffb8d5779728998be/factions/elves/units/academy/models/academy_cons.g3d

But when I imported it into Blender before rescaling the model, the texture for that object didn't come with it. Though it shows up correctly in the game and the megaglest_g3dviewer app.
