There was an intermittent exploit on Luca new quest because....
...This is TMWA.
TMWA code only works when it wants to; For weird reasons beyond me the quest code only worked on localhosts
So I changed the syntax of the quest and restarted the server, so it should be working well now.
The quest was reset!
If you already did the quest, you'll have to return the assassin set items on login. This is done automatically, no action from your part should be required.
If you do not have all the items to be returned, it'll be attempted later until you do.
Storage is NOT checked, be sure to move to inventory and relog if you stored the items.
...However, Luca won't work for you until the items are returned.
Which means you'll be stuck without being able to focus or unfocus.
The patch is already live, in order to avoid evil people from trying to further exploit/abuse tmwa vulnerabilities and bugs (which are more than the hair on the dev heads... No, I'm not looking at you, jak1).
Thanks for playing The Mana World.
