Both will be reworked and reintroduced at a later point. They likely want player to focus on playing and giving feedback on all the new ones. Think about it: It's the first time the game ONLY has textured Maps and no whiteboxes now. Gives a nice impression on youtube, when recent videos only feature finished looking maps. Farm is probably the roughest one too date, as it is the one most desperate for a remake. All 5 new ones look stellar.
Thanks for your words. And yes, Farm actually has a brand new whitebox that is just about ready for art.
