Whether it's intended to happen or not, I deleted a Kaiser that had the Reboot Warrior Link Quest due to lack of available time and found out that the quest does not reappear on any other existing warrior character. Making a new one doesn't do anything, and I had waited until maintenance to see if it would reappear. This concerns me as I've been really looking forward to getting the master class medal, but now I'm not able to because the warrior quest is unavailable.
Yes, I know that it said that you can only accept it on one character in Reboot. I'm just not sure if it was supposed to be permanently unavailable for other characters of the same class if you deleted that character, or just a serious bug that hasn't been noticed.
