HwangSa random search quest is buggy

[o11c]

• Often I recover some artifact, but the quest-giver isn't interested in taking it back, just because I used a skill on it.
• I've been accused of letting the monolith be destroyed, when all I did was use a skill on it it.
• It is really easy to go over the time limit. This can happen e.g. when going up stairs in one of the dungeons.
• Memos/emails are sometimes outdated.
• Sometimes, as soon as a mission is failed, it immediately advances as if I succeeded.
