I was on earlier and a strange thing happened. I opened a gate from inside my house to Blighted Grove and when I went through it I saw a few KOC and LOW fighting. I came back through the same gate and KOC and LOW followed me through. I immediately stepped on a teleporter to go to the 2nd floor and was supprised to see a LOW guy beside me on the 2nd floor. He used the 'friends only' teleporter to the 2nd floor. I banned him and then checked my teleporters to find the access to them set to 'anyone'. I suspect something in the latest patch reset the teleporters access to 'anyone'.
Thanks for the heads up
Egads! They will steal all my lovely purple shoes. :'(
