Server down on multiworld

[DrMasik]

I found stable solution for server down

There are 2 players. First login to World1, second - World2. Default for all other players - World0. All names are lowercase.

When player spawn, I check login (GetName()) and move it to needed world (World1 or World2) into home as building. So, let show me cut of code:

function Initialize(Plugin)
-- ... Cut some code
  cPluginManager.AddHook(cPluginManager.HOOK_PLAYER_SPAWNED, MyOnPlayerSpawned);
-- ... Cut some code
end

function MyOnPlayerSpawned(Player)
-- Cut some code

  if Player:GetName() == 'test1' then
    Player:MoveToWorld("world1");
  elseif Player:GetName() == 'test2' then
    Player:MoveToWorld("world2");
  end

  return false;
end

-- Cut some code

And there I have 2 bugs:
1. Player test1 into there home building, but, in world0. Home "copy" from world1 in to world0 and destroy world0 area where home "copy".
2. When player disconnect - server go down (core dump).

Server console log:

Code:
