I too vendored about 1 million credits worth of these two materials. I'm a little displeased by this decision on the part of the devs, I have to say. It just seems a little inconsiderate on their part, to establish a new scenario and then go back on it after release of the product. It would have been better to have the option to convert all these mats into the currently-in-use mats or credits. My point is, many of us have been saving this stuff up, along with the green quality mats, for a month, striving to gather more of the usable stuff, only to have it yanked out from under us. Doesn't seem very professional. Better option still would have been to introduce better new patterns which did use these now defunct mats, patterns for actually desirable products.
