Just did it for the 4th time this week. Yes that's nuts but I'm using double xp to get alts to 120. This one was Paks on Maj;Dul. All was fine as I did the two plane of innovation dungeons. When I went to cash it in I expected 6 levels based on past experience - this is a very high reward quest even apart from server bonuses. Instead I got nothing. The character got quest credit and can now do plane of disease. She got cash - one platinum. She got status. No experience whatever. The AA slider was on 0 - she had been getting normal experience all along other than this quest cash-in. I checked of course and it was set to convert 0 xp to AA. The quest just gave no xp at all I checked chat to see what it said I got. No xp was listed. My other 3 times were before the last patch and all were normal. The patch may have broken something.
