World name:
Gilgamesh

Character name:
Miharu Azanami

Steps:
1. Log out while visiting another world.
2. If you have Entry level subscription (limited to one character per server) you are able to log into the next character in the list while char #1 is world visiting.
3. Able to do this as many times as needed.

Not sure if this is intended but it feels too much like an exploit.
