there's just a loading bar every time I try to take a turn, no matter if I'm using Chrome or FF. Windows 10. pls help

There should be a forfeit link here under your battle pet's name: Statistics

Is this a common error? Do I have to forfeit?

edit/ also, wtf... all my battle counts are 0

@ ghost: The challenger has retired so it might explain for the page not loading issue you're having, because well the opponent is not there anymore. I guess there's no other option than to forfeit it. If you engage in another battle but still see the same loading issue then perhaps it's the site's problem. I've been having slight issue with battling for the past couple of days myself, though I guess it's because the staff is upgrading the infrastructure. Other than that, battling has been quite stable for me for quite some time. The lag during the first few days of Survival was unfortunate, but it didn't last long.

Interesting. Same thing is happening now with a fight with Manticat. :T maybe it's the site...

With the Manticat, are you trying to select more than 2 weapons?

There are two common reasons for battles hanging:

1. You've clicked on more than 2 weapons. It sucks, but you can't fix this from within the battle.
2. Your internet connection or the site went down for a bit (I live in Aus with shitty internet so guess what always happens to me?). The page hangs. You can try waiting this one out but usually it's best to do as below:

Solution to both: Close the tab, go back to the main challenge page of the coliseum and click on any of the 'you're already in a battle' links. Don't forfeit.

If the page hung after you clicked to end the battle, close the tab and either reopen as above or try to start a new battle (just reopen the BQ page if you were doing BQs). Sometimes the next few battles will glitch out and sort of auto win. Mostly they won't.

Yeah, I guess I was clicking too many items. It's a weird way for the system to react to that -- shouldn't it give a warning or an error instead?
