Can someone knowledgeable please impart some wisdom

I have just gotten internet hooked up to the new flat I have moved into this year and logged into nord invasion to see that the naval glaive and jormungandr I had on my pikeman are now red legendaries and the barbutte with coif is orange. Have they been changed to drop from different bosses? And is the barbutte house craftable now? Thanks in advance
