We both see this generic Mii when we go to friends list and it lags horribly between us too. We managed to stop lagging but this still shows. I took this pic before we deleted eachother to try again. No dice still shows this. It won't update any information for eachother.
No. I'm not banned or anything. We can play online together seemingly but we disconnect from eachother a lot. We played MH4G in January perfectly and now in MH4U it disconects us a lot.
