If there are new blueprints, you will need to refresh the palette of the appropriate catagory, i.e. creatures, refresh creature palette.
There are some updates pending with some major amount of material, such as clothing with over 14,000 models added and ridable griffins, some other materials. These will be in when they get there. The new tilesets Chico400 delivered are being merged in - all his tilesets with the exception of the SF tilesets and those we have plans on adding as well.
So yes lots of things are coming but all i can say is soon, since this and that have delayed the updates, such as Acaos's motherboard and ram frying, and other little annoyances like that. The material IS coming soon.
ROAR - the crafting system i posted is shaping up but not ready for release yet, perhaps by end of August.
