Bug on NPC Natools

[CunY]

Hi I have a problem with the Natools quest, I'll explain, I finished the quest "Fallen Angel - Request of Dawn" back from Natools, which has a parchment over his head, I click on him but the next quest "Fallen Angel - Request of Dusk" is not displayed.
Why?
Is there anyone who can help me?
Thank you.

You can only do 1 Fallen Angel quest from the Shadow Fox Quests:

If you choose Dawn https://l2wiki.com/Fallen_Angel_-_Request_of_Dawn

you turn in quest in Gludio Temple to High Priest Raymond

If you choose Dusk  https://l2wiki.com/Fallen_Angel_-_Request_of_Dusk

you turn in quest in Gludio Dark Elf guild to  Grand Master Tobias

I got it!  Thanks for your help.

But I do not understand why he has the parchment on his head, as if to indicate that he would like me to do another quest, what is a system error?

It's not really a system error, just normal sloppy design. You will see the same phenomenon after you have done a daily quest in the post-85 levels. After you have finished the quest and gotten your reward, the NPC gets the parchment with the green ribbon around it again, but when you talk to him, the quest is greyed out, i.e. it can not be picked up until the next day at 06:30. The parchment just means that there is a quest in your level range, but due to other factors you can't necessarily do that quest.

Thanks for the reply, at least I know that when I get the same situation, it's not due to a bug.
Thanks so much.
