Actually..... yeah. I'm an idiot.
I had submitted around 8 replays or so (can't quite remember) replays in the same email a while ago. Then a little while later (just a few days) I was given a tip that I should resubmit the replay that I wanted most featured in case you hadn't seen it. Given that it was my first replay submitted (and I didn't quite know the rules), I heeded their advice and submitted "ShadowV2" again. I suppose it was that which caused the replay to be featured twice... I still am unsure why they were so far apart in the show though, seeing as how it was submitted, then resubmitted in such a short time frame.
Sorry for the inconvenience. I know how hard it can be to get on the show, and it's not fair to be featured twice with the same replay. I'll avoid making that same mistake in the future so I don't upset any fellow replay makers.
