When I updated my workspace to build 684, I decided that since the method names for renderBottomFace/etc had changed I would rebuild my rendering code to be a bit more streamlined. However, this is currently happening, and I'm not sure why, seeing as rendering is such a pain.
Here's the project in question: https://github.com/Shukaro/Artifice
The code in question is under artifice.render, and artifice.util.render
Solution: I was passing duplicate vertices to my face rendering functions, as well as using the wrong method for getting their icons.
