GAC unassigned me When battle phase started

signed up for gac like usual (Mid K2). Resaved my roster to gac as I was fighting time to get the Hera focused cron. Setup phase came and I scouted my opponent. Battle phase came and I am suddenly not in a gac match anymore. Tells me an event is already in progress and to check back when it's over. Spoke to in game "help". told me I didn't sign and to get lost. Cool Response CG!
