What gives? It's not even a specific side/edge, the parts of the face both at the beginning and end of those lines look fine. It's just the middle of them that got fucked up somehow. The 100x100x0.8 square I printed as a test before it came out fine, and it covered the same area of the bed that the messed up part of this print was in.
