Found a bug while doing shaman water quest. By that I mean I wasn't able to turn in a part of it (think it was the Brinne part in southwestern Barrens). That was caused by a questie LUA error (nil value).

Edit:

error states: Questie.lua:336

Which version are you running? This is critical because in the latest version line 336 is:

local req = QuestieHashMap[questhash]['rq'];

There are tons of quests that I've personally done where that field doesn't exist. This line has also been present in Questie since before I started improving it.

2.65 (latest one I guess)

Might have something to do with that NPC called Brine or Cartographer idk tbh. But I disbled Questie and was able to turn in the quest. I had no other addons than questie.

Can you do me a favor? Will you edit your copy of Questie.lua and add these lines?
Old:

function Questie:finishAndRecurse(questhash)
  local req = QuestieHashMap[questhash]['rq'];
    if req then
        Questie:finishAndRecurse(req);
        QuestieTrackedQuests[req] = nil;
        --DEFAULT_CHAT_FRAME:AddMessage("Requirement: "..req);
    end

New:

function Questie:finishAndRecurse(questhash)
    if QuestieHashMap[questhash]['rq'] == nil then
        return
    else
        local req = QuestieHashMap[questhash]['rq'];
        if req then
            Questie:finishAndRecurse(req);
            QuestieTrackedQuests[req] = nil;
            --DEFAULT_CHAT_FRAME:AddMessage("Requirement: "..req);
        end
    end

ok, done it but as I said I had completed the quest allready :) I will report any issues if they appear.

Wait... I forgot about something. :D You don't want to do that. Remove the word "return" like so and save it:

    if QuestieHashMap[questhash]['rq'] == nil then
    else

Allright..

v2.66 - new version. Should be fixed.

When you open your quest log, select a quest, is the quest level present? Should be in the main list but I'm talking about the large quest title at the top of the quest summary frame, not the quest log list.

[30] Some quest title

Please test again with the new 2.67 release.
