I just gobbled 51 Stacks of Zhaitaffy. (edit, since no one seems to be looking at the screenshot: I gobbled them at once. I Clicked Buy only once. I bought 590 "Zhaitaffy Gobbler's Blessings" at once.)
I got 1d12h worth of the Dragon Bash Boost (I think I had about 3h of it before), 9 Dragon Coffers and a chat box spammed with "You have reached the maximum duration for this boost".
All my Zhaitaffy is gone. There was no warning about the Buff having a limited duration. The Celebration Buff for instance has been stacked up for over 23 days on the same Character before.
I feel a bit cheated, Is there any chance I get my Zhaitaffy back?
Here's what it looked like
