OK, the reason why we (unfortunatley) can't have any more maps to explore in FH at the moment, is because the creator of the game, KovuLKD seems to have vanished out of thin air and even the staff can't seem to be able to contact him.
He's the only one who can add "official maps" to the game, which means that no "fan-made maps" are going to turn into ones we can all access any time soon.
Some people think he's abandoned FH all together, but I'm pretty sure that's not true, so until he decides to emerge from his slumber, no new maps can be added (or any updates at all in that matter).
It's a bit annoying for us all, because some of us expected get a "Christmas present update" like we did last year.... but it looks like Santa/Kovu has decided to drop out this time
However, don't smash your hopes into pieces yet, there is still a possible chance of an update (even if it is sometime next year) and who knows..... maybe our luck will change
