well see every time like stefan realeses the new map then like the day after there is a huge update on the map... (Good past example is like the rail roads and church and stuff)....
good example right now is the moon...
then like he doesn't realese a new map until like a new version comes out (but he does few updates to the map inbetween the time something big happend on the map and the new version)...
it seems to always happen like that..
