Quests reset?

Umm... did anyone get some of their quests reset after this week's server check? I was checking up Ulu City quests on my quest log... and somehow there weren't any. I got as far as the final quest (to defeat the tree lolo), but when I checked under In Progress, it was nowhere to be found. Instead, under Available is the first quest "Savior of Ulu City."

And no I'm not crazy, since I did these set of quests with someone else, and she too has them reset. Anyone know what's going on here?
