I've already updated the game folders with the latest patch.
As many other people have already noticed, the trainer avatar doesn't show up when the battle begins (and also on the trainer card: there's Marianette instead of the usual male trainer avatar). More importantly, after upgrading to V10, my Decidueye (nicknamed Sagitta) had its Spirit Shackle move swapped with Steam Eruption (???).
