Wouldn't you know it? Not 15 minutes after releasing version 0.02, I discovered a graphical bug that I haven't encountered a single time since starting this game in November. A re-bake of occlusion culling took care of that in no time. And here's a bonus, as well: I compressed some textures (okay, most of them) and reduced the file size from 800+ MB to just under 400. Wow!
