I'm not sure if this where I should go for help with this or not, sorry if this is the wrong place.

Even though my pet has 10/10 on happiness and hunger and isn't currently in training every time I go to the Battle Coliseum I get "Oh no! None of your pets are eligible for battle. You might want to make sure that they're well fed and happy!" below all the opponents. I don't normally battle so maybe I'm missing something really obvious, but I've been wanting to try the special holiday opponents (this also happened when I tried to challenge the bopper). Any advice?

I use Google Chrome on a Windows computer, if that makes a difference.

Is your pet stuck in a battle? Check the status page.

Where's the status page?

That's it. Wow I feel really dumb now.

It happens. Usually during lag or downtime the fights don't get completed and the battler thinks they already pressed the button.

Thank you for your help.
