Added the log.

I am getting a similar texture issue with this mod. Specifically the printer texture is broken as of today's patch. See below for one of the error messages.

Same problems here

Missing or bug droid fabricator texture.

I'm also having an issue where the textures for items from this mod are not working and replaced by a red ? on a white square. I am on 1.6 and Everything else seems fine at a glance, just not textures.
