Things that worked before but now don't

This is my understanding: the objects are rendered using alpha testing, which looks to see if a pixel's alpha is less than a threshold value (which I have set to 0.25), and makes the pixel opaque or transparent depending on the value. Since the texture is bilinear filtered, the alpha values get interpolated between pixels. When rendered, the areas between the texture's opaque and transparent textures will end up with intermediate alpha values and pass the alpha test, and because of the bilinear filtering they'll have some of each neighboring pixel's color. As a result, they'll pick up some pinkish color.
