I have managed to get a local cluster up.
Had to to revert the cluster security code since the secure cluster code did not implement all the functions of the ICluster interface the world and voice server require.
I am using the enUS 2.4.3 client.
The client crashes immediately after the [09:43:15] [127.0.0.1:63588] SMSG_CHAR_ENUM call with a divide by zero error.
@wowadict any thoughts?
