Clothcraft materials missing?Follow

Has anyone who does clothcraft realizes that in the past week the supplies of lots of materials like silk thread, cotton thread, cotton cloth..etc. had decreased a lot? I was trying to find some cotton thread today and there are only like 2 stacks in total for all the AHs! Then I guess I would desyn goblin armor for it, but guess what? There arent much armors left too! What had happened to all the materials?
