Every now and then a replay get corrupted causing glitches in the replays, it really can't be help besides editing the replay yourself to try you best to match the outcome you're wanting. I absolutely hate when that happens, had some really old replays get corrupted as well.
Its definitely a common problem.
It mainly has something to do with the dl
try reconnecting when this kinda stuff happens
It happened to me the other day in ABD it said
it was 25 frames but it was actually a 50 frame turn causing
me to dq thinking I had time also causing this glitch
Try /rec when this happens to you.
Come back if that doesn't fix it
As far as the replay it self I couldn't tell you how to fix that
