I purchased another Kaih and my mistake was not to buy him to the level I would have gotten him to level 10 as I had one and was thinking if I purchased him rank 2 since I had one already would be able to go to level 110. My mistake.

But I was feeding him to level 105 and had him to 70 or so and when I came back later he was to level 10 again and I had to start over. Not sure if anyone else experienced this but I lost a lot of food ... Thought I was tired and wasn't going to report it but I am positive I did have him leveled to 70 and then all of a sudden he was down to level 10 and I lost food and time. Anyone else?

Also make sure to send a support ticket , like this

I've seen this happen when you get disconnected while playing. Not sure why the food was gone though when you saw him back at 10 - maybe the food collection didn't register? So maybe you didn't lose food, you just never picked up the food from the disconnection issue.
