Well the map formerly known as gm_kh_construct has become gm_ElysiumTown_beta has has some major changes, for example. There is no longer a construct area, it's just RP. It's still in the works and hopefully the next release will have the lag fixed. Some pictures are at http://forum.facepunchstudios.com/showthread.php?t=130125
