For a few weeks now, while on my desktop, I would be clicking through the quest lines and the quest frame will blink out and come back on....usually while aborting quests to get to the ones I'm able to complete. When this happens, the quest line I've aborted will not refresh with a new quest, leaving a space where a new quest will normally pop up. When this happens, the remaining quest lines become unresponsive and I'm only able to close the quest tab entirely. Once closed, it will not reopen unless I refresh the game. Only happens on my desktop, never on my tablet or phone. Not the worst glitch, but it can be annoying when trying to sync certain quests with collections.
