Due to the large ammount of hax on simulators war battles were unofficially ruled by guild leaders years ago to be bo3. The only time a bo1 war occurs is when the match is over wifi to avoid matches which go for an hour or more.
As an additional point, Rest lasts about a round. Since Rest was the only move that Miror's Pokemon used last round, and it was used early in the round, it's reasonable to say that the Pokemon would wake up on it's own mere moments after Fierce received her Meditate boost.
Hey so I was reading your match with Miror. Here's the deal.
When ordering first, the trainer has every right to edit their orders until their opponent posts orders.
When ordering second, the trainer may edit orders until the reffing is posted, BUT if the referee sees the post and starts the reffing prior to when the edit is made, they are by no means obligated to alter their reffing.
Unless I'm mistaken, Miror's edit was made approximately 14 minutes before your orders were posted. As such, unfortunately, you have no case for a re-reffing.
