Kiya, this doesn't effect my game or the play I'd just like to know what quests I have and what quests I've finished. I unchecked the filter quests log and it does show my entry into the catacombs as complete.

I killed both assassins so I guess I was supposed to not kill the guy who gave me the quest and maybe that's why the quests is still listed as unfinished. There should be an item for failed quests or something.

The Merchant's amulet is just broke for me. Whether I tell him the truth or not the quest stays there and I think I get more stuff by not telling him.

Didn't check the XP but it's too late to go back now.

Oh well, I'll be in Act IV soon. Hope the diary works better.
