As of Patch 2.3, if you get a message "Interface action failed because of an AddOn", this means that an AddOn interfered with the Blizzard UI in some way. To diagnose this, enter the following into chat "/console taintLog 1" and restart the game and try to reproduce it. If you reproduce it, you can quit the game and search through the file Logs\taint.log for the word "blocked" and mail the log to the author of the AddOn listed there. Once you have done this you can turn off logging by entering the following into chat "/console taintLog 0"
Then I made my way inside the cave in Stillpine Hold to complete the last half of the quests: inspect the blood crystals, kill Chieftain Oomooroo, the 9 Crazed Wildkin, and The Kurken. Only it took me a while to get to the cave. I didn’t know the quest was inside the cave so I tried using the waypoint to find the location, but it directed me on the other side of the mountain. Which was quite far from the cave.
A handful of us donated to Whoknowsit to so he could buy ALL the upgraded guides for MoP for all of us. That was an investment into THIS community not into torrents or into any other. We want it to remain safe for us to continue to use. Whoknowsit is smart enough to know what to look for to take out Zygors' tracking info, but he knows he is NOT perfect. That is why he is STILL careful.
Well. LFG is designed to replace blizzard's premade groups entirely just like custom raid frame addons (like grid, grid2, healbot) did towards blizzard's compact raid addon. We can actually do little customization towards Blizzard's UI unless we write our own "UI". Instead, just use LFG to create/search groups instead of blizzard's UI since it sucks.
