Suppose I speak in chat then switch character. For example, I make a deal with a char I'm currently logged on then switch to my crafter to fulfil the contract. I prefer to see what I said 1 minute ago with my other char (and not what I said few days ago with my crafter). So I want one (common) chat history for all my characters. IIRC firstly it worked this way. Are there some settings to choose this mode?
