I think switch 0478 is just the encrypted version of switch 0071 which return the charID, map name, map ip address and map port. It's just like the previous update, they changed the switch for logging in.
It's seems Lyto will update it weekly.
'0071' => ['received_character_ID_and_Map', 'a4 Z16 a4 v', [qw(charID mapName mapIP mapPort)]],
I tried to copy this and change it to 0478 (and also added it to recvpackets.txt), the openkore got error because it can't find the field file. I hope someone decrypt the packet.
