Set about to investigate the new block types and built something with combat steel. Re-affirmed that I still dislike the sathium requirements for hardened/combat so went to utilize the replaceblocks command to change material type and discovered something interesting: That looks a little funky!(even for me ) So I went back to the console: and then realized the new changes to the "atlas" means that the generic switch between types(combat, armored, concrete, etc.) and thin/large are no longer enough. It is not immediately intuitive but the type and the block address matters. So not only are there new types like "extended" but there is/are atlas specific referencing; "extendedlarge3." This has always been a functionality of the command, but it was not wide-spread knowledge; and the new block types force the issue. Use the debug info menu(type "di" in the console) and aim at the block type you want to replace just to make sure. Apologize for the double post if this has already been discussed, but I hope this helps!
