This weakaura makes the lich king get angry at you when your Contract: Talanji's Expedition expires after the change to make them last 7 days instead of being permanent. I don't mark my calendar and didn't want to accidentally not notice it falling off. I've never made a weakaura before so I don't really know very much about these. Don't run this weakaura unless you're actively using this specific contract, because it simply just detects if you're lacking the buff and thats the trigger. Obviously you should switch it out for another one if you're switching contracts.
(I did not have a horde character at 120 to directly test this weak aura to see if it functioned, but all I did was change the spell name)
