Well, something has definitely been off - because earlier this week I lost my celecstial coins on all but one character. And I had been online and done invocation more than once a day and I know for a fact that the day where they were gone I had done my invocation late afternoon the day before, but it was before noon on…
I just logged in today - I have been logging in multiple times per day to do the invocation, and on all but one the celestial coins had been reset to 0 :( I have submitted a ticket, but seing the responses that zombieelvis has gotten - my hopes are now very low that I might be re-imbursed.
