When I'm battling, I have to click on two weapons to attack with every single time, instead of them being automatically selected - the same with scrolls, too! Did something change?
When you go to challenge an opponent (like so), you need to click the Preselection Settings in the grey box below your pets. "Preselection is currently OFF. Click here to turn it ON." It's off by default and needs to be manually turned on. If your browser ever gets cleared, it'll turn itself off again until you turn it back on.
