Mangos 1.8.1 - enabling teleport to azshara crater

[Azsharianin]

Hi,

So I made custom zone inside map 37 - Azshara Crater. Now I wanted to add npc with gossip option to teleport player there, but it's not working. When I try to use it nothing happenes, the same with ".go xyz" commands. I got error in logs:
[20:32]: Player::CheckTransferPossibility: player Player Rienyoki (Guid: 8197) try teleport to map 37, but entrance trigger not exists

".go xyz" commands works only with gm mode on. Now I was googling on how to do it and all I've found leads to changing info in worldstate_info or something like this in database, but I don't have anything like this. I made sure that map 37 is not set as battleground in maps.dbc - it's okay, is set to "normal" zone without any level or min/max players restriction (at least in mentioned maps.dbc). So, what should I do to allow my script-teleporting?
