So just tanked scarlet monastery to get the quest done in there while I was low enough level to use LFG. Checked the log after to make sure there was no hiccups and found the quest is now missing from my log. Not only that but many other quests are missing (most of them completed). You see, I will do instance quests then wait to turn them in so I can squeeze in as many normal quests before they grey out on me but before I am too high to use LFG for that instance.
Also, not a big deal, but have abilities that poofed from my action bars.
