Horde guide showing Durotar at 98%

[krush11]

So I have a Troll Hunter and working through the Zygor guide from the start, I have finished all the quests it's given me and am now on to the Barrens. BUT... The Durotar guide shows 98%. I cannot figure out what quests I missed (or how I missed them since I followed the guide). The only ones that look incomplete (not green) are 142 Talk to Kor'ghan, 143 Kill Venomtail Scorpids, and 144 Talk to Korghan. However, I already did those as part of that one quest to find the cure for the troll guy. I went back to Kor'ghan and he has no quest to give, so not sure if those are the culprits or not (and I don't understand why they are not marked complete in green since I did them).

On my other Orc character, Durotar is marked 100% with a check mark. I hate seeing that guide not complete, so any suggestions on what to do or how to see what is missed?

The completion percentage is just to give you an idea of if you've done it or not and there are many things that could affect it making it not show 100%. It's probably something minor like a class quest for a different class that the guide viewer isn't ignoring properly, or something similar that is nothing you missed. If you've used the guide and you know you've done the steps that it told you to do then you can ignore that completion percentage.
