For the playerhouse box, there needs to be a command for selling the house to another player.. because Loriel seems to be the only one that can do this and he is away.. And I have been trying to get my house sold for weeks..
Stefan, just add the command "sell house for <ammount> to <account>"
The player buying it has to be in the room.. the box will ask the player to accept and then if they do they get the house.. just like bomy's.. It's something that is definitely needed.. I hope you add it soon =)
