Zones are available, zone list is on the left column, just say the shortname to the teleporter
Some zones have 2 versions pre & post revamp - sro-southro oot-oceanoftears etc
Nek forest also has 2 versions but used the same ZoneID so only one is available, same for lavastorm and maybe others
The server probably uses the old versions while the client has revamped versions so not compatible
All Emu servers have the same issue, maybe they addressed them
If you have a titanium client, you might be able to go to them if you just want to look around, not tested so maybe wrong
But for the most it should work fine, although they may be empty as any zone not used on EZ will be just at default setting
