Lost Texture on Imported Object

[Mazz]

Hey guys, 

I think I made a mistake that might not be salvageable, but I wanted to check in with you and see if there's a way to fix it.

Here are the steps I took before this problem happened:

1) Imported the whole mesh into 3D coat, all in one UV Texture and one material, and began painting.

2) Had to make a change in Maya, and ended up exporting the character out again, except this time I forgot the wings.

3) When I noticed the wings were gone, I went back in Maya and exported the entire character out again.

4) Using Import>Replace Geometry, bought the whole character back in but the wing texture was missing, and instead you see these tiny little squares with what used to be some of the colors I had in there.

I spent a lot of time on the wings so far and I have a feeling I will have to paint it again, but is there something I'm missing here? The texture was there until I imported the mesh without the wings. Does that override the texture?

Does that override the texture?

Probably, it is always better to work on a new version when big changes are made.
