A bit of a bug where doing an Account Reset does not reset the quests.
Second time this has happened, but today it took more to undo it.
First time:
Not sure, just did an Account Reset. After beating AIs 0-2, I checked the quests.
I was able to receive the reward for ALL quests, thus getting a rare card.
FG and Upgrades were then available.
Second time (today):
Had my fortune done, decided to do an Account Reset.
First battle on new I noticed I had the Oracle's Pet.
Decided to check out the quests, same thing as above.
In order to undo the quest bug, I had to do an Account Reset again, NOT get any rewards for any quests, another Account Reset then clear all browser history.
The browser history was to clear out cache and cookies mostly.
Refreshed the web page, relogged in and another Account Reset finally reset the quests.
The problem with this quest bug, if my assumption is correct, is that it messes up your score.
With a fresh account and all quests done, 1 win and 1 loss put me at a score of -3.
A fresh account with 1 win and 1 loss has a score of 8.
It looks as if the 150 and 500 score quests interfere with your normal scoring when this bug happens.
I tested it out, and the above scores are both with a fresh account with the first battle as a win with second battle as a loss.
