fix(maps): Arkania is map number 82 (client World = number+1 off-by-one)

Client tried to load World84 for map 83; MU client world index is
server map number + 1 (Lorencia 0 -> World1). Arkania client assets
are World83, so the server map number is 82 and the terrain resource
is Terrain83.att (number+1).
