Are you sure they were actually switched? Because I'm not sure they really were as far as crafting them was concerned. The recipes for each of the different daub colors are built around the color of the daub they produce, e.g. green daub requiring peridotite sand, orange daub requiring bauxite sand, ect. With this change, however, light brown daub requires very lightly colored materials (limestone/chalk sand, blue clay) and produces a daub that is darker in color than the weathered brown daub, which is created using much darker materials (chert/phyllite sand, any clay). I'll probably submit a bug report on this; at the very least the recipes probably need to be switched if the texture change sticks.
P.S. Might I suggest just changing the name of the existing blocks instead of swapping their textures? I can speak from personal experience that this change really disrupts existing builds using either of the impacted wattle and daub blocks...
