Group disbanded due to server maintenance

so i was in a match for my promos for gold 4.. had 1 win 1 loss.. at about at 0230 (UTC-7:00) Moutain Time (us and canada) on 06/27 after we all picked our champs waiting for load screen to kick off.. we all got kicked out of the match.. it said the group has been disbanded due to server maintenance.. i checked and they put down ranked que.. but the issue is.. it gave me LOSS for my promo.. says i lost my series due to inactivity?? -.- has to be a bug..
