Summarize your bug I won the GAC battle against my opponent who didnt put up his defense, apparently. I won against his R2D2, Jedi Training Rey and Commander Luke with Emperor Palpatine, Thrawn and Bastilla Shan Fallen. It would have been the last team before I could go on to his ship section. I try to get banners for better rewards. After beating them, it says the connection was lost. I switched off the wifi to mobile. Then it said I got 53 banners. I was happy, went back to the main screen of Grand Arena - And the team is still there. And it says "1 fight". Clearly a bug.
