This has come to my attention...

Some people are having problems with Textures or Windows/Doors. 

I only use Peacemaker CC for these objects, they become colorful with the (?)

Example:

Apparently, he had to add these files to his furniture, windows, and doors. I wasn't aware that they didn't show up when I import builds. These are the texture files that he added that may help you! I'm not sure why it doesn't include in the files.

You don't need to redownload any builds as far as I know by adding these files to your mods folder they should appear correctly.
