This is a major inconvenience. I try to keep my inventory neat with my resources in different packs. However, you can only seem to use a resource for crafting when it is NOT in a pack, but is in your general inventory. This is quite a pain. How come the resource is not available for crafting no matter where it is in your inventory? Does anyone else think this is a problem?

Thanks,
