I recorded my first official game with an ITS code last night. My profile shows 2 W - 2 L. @Narkano is shown as defeating me and I've never met this person. Iszilzha is shown as defeating me and I've never met them. Rainanddray is shown as losing to me 10-0, and I've never met this person. Again, I have only played one recorded game. The only official opponent I've had is TacoShank. I beat him 9-1 last night, as recorded.
Check it again in a day or two, but yeah I have heard of Aristeia games getting mixed up with ITS some times.
