Can you go back and check, and take a screenshot? 

Sure, what exactly you require me to take a screenshot of?

The same exact thing happened to me. I ranked up my Undead Banshee to Rank 6 with champions and a chicken, and the next time I logged in the Undead Banshee had reverted to Rank 5, and my feeder champions were also gone. I put in a support ticket this morning. Can't take a screenshot of something that is no longer in the game. Don't you have backups?

Hey LadyWolfe, I suppose they must have archive in the server info (that is what i expect based on my experience of contact with Gm's at WoW), but with the current situation im afraid it only makes sense they ll require some time to work around this issue. Lets hope situation gets better over Ukr, so a moderator can help us find a way out of the problem.

Sorry for the delay.

I'm not saying this is the case for you, but we've had people claim similar bugs and it turned out they were just looking in the wrong spot. So I just need a screenshot of your roster where  your food champs are. And then send me a DM with your um#  

I get your point of view sir. But its kind of unlogical for me to have s screenshot of my champions before i used them for rank up. I literally spent more or less about 3000 energy during those 12 hours of gameplay for the cvc, leveling food champions 1 to 2 to 3 to 4 rank...it would be insane for me to take screenshots of each step before spend 10 minutes in tavern upgrading them. Isn't there a way for you to check my status for that day, more specifically at that time? It was between 00:00 and 00:20 monday night (first day of cvc) GMT+2. That considering i understand you request a screenshot of the champions i lost- i can always take a screenshot now, but i obviously have 100 different champions up now leveling for food.. thank you for your time in advance.
