Event:PARTY MEMBER CHANGED

Triggered when something in the party changes. These are the causes I've found for this event: arg1 sometimes text of what has happened e.g. "[Player] joins the party" or "Class change to:  Lv Lv" arg2, arg3 and arg4 contain some values where I couldn't find any pattern or logic behind it. At least, there seems to be no parameter that tells you what happened, so each time you receive this event, you have to check for yourself what really happened. -BuffyS (-Updated by Bizzarrus)
