I'm battling and about every second or third battle, when I attempt to battle the challenger again, when I click battle again, and then start battle, I get the error: Oh No! You can only attach 8 weapons! I am not trying to add more weapons, I am no where near my weapons. I have to go back to the challenge an opponent page and start a new battle from there. It doesn't happen every time - as I said, about every second or third battle.

I am currently using firefox (however it happens in chrome as well), windows 7.

Could it be that you are trying to click too fast after ending your previous battle? I find that a lot of the little battle glitches like this are the result of trying to rush through everything, slowing down a bit could help.

It happens when the Preselection weapons feature is not fully load and you click on "start battle" very quick. wait a second or two for it to be "on or "off" depends on your choices and then start the battle

Thank you both - I could definitely be clicking too quickly for the preselection to have loaded completely.
