I'm having similar trouble with a multiplayer server and builders. The architect drawing table appears to be working, and when I check the blueprints folder the blueprints are there and appear to have the full contents I'd expect. However, when I place them into a builder nothing happens and the materials needed menu is blank. Normally I'd expect to see an outline and the materials needed in that part of the dialog. My client is running on Windows 7 64. Probably not super relevant. The server is running Ubuntu 10.04. I'm not getting any error messages that I can see.
