I have gone through this cycle twice, across server resets. It's for https://bbb.hidden-street.net/quest/world-tour/cupids-courier-magician-only. After delivering Richard's Letter to Angelique, the letter does not go away, although the quest shows up in Complete. Once the letter is dropped, the quest shows up in Available again. I know the quest is repeatable, but other repeatable quests stay in Complete, not in Available.
this quest can only be completed once in Maplesaga. you can ignore the quest pop up. there are more quest that has the similar to this. for example quests from aquarium.
I have actually completed it multiple times though, it shows up in Complete if I keep the letter, and switches to Available as soon as I drop the letter.
it seems for you to complete multiple times, when u click "ok" button the pop up prompt will disappear with nothing else pop up right? it will only register you for doing the quest once. you can still click multiple times for the quest as you like. another possible quest i could think of is in the henesys chief stan quest. (i will check when i reach home to edit this point)
Not quite, after I take the letter to Angelique, I get quest rewards (like 3 watermelon and stuff). If I drop the letter, I can retake the quest from Angelique, take an ETC to Richard, get the letter back to Angelique and get the rewards again, like I never completed the quest before.
OK I talked to a few people, this quest and the quest that rewards the Magic Seed both have the problem, only solution is to keep the ETCs...
