Here's what happened. I just won a 1k duel against tr1ckle. So I was going to spectate because that's all I wanted to play. But after I won the second match instantly started without me pressing the space bar, at the same times I spectated. I lost my 1k, but noobstatus said he didn't get any tc.
It's not a glitch, you probably lagged a bit which made it seem that the next match didn't start, so you spectated, but really the match had started so you lost your 1k and the other guy lost his.
Sometimes it will glitch and start emediatly or tr1ckle was running a script.
What helps is to turn duel mode off and spectate after the match so even if the fight starts you and the other player wont lose thier tc.
As for your loss there is nothing anyone can (or will) do. Like firebolty said you can ask a GM to refund you but on most chances they wont.
