We are aware of the bug currently affecting ELO which is not recording scores. I have personally reported it. Unfortunately it's 4am in France. So please be patient. We will let you know as soon as it's fixed.
Oh so here's the deal. It's not a bug. From Midnight to 4am Paris time on Monday (3pm PST to 7pm PST on Sunday) ELO goes into it's 'dead zone'. Basically fights don't count towards scores or whatnot. Consider it a time to get a feel for your new decks.
