I never really got round to reporting this so it may have been fixed now since I'm a year late, but in case it hasn't, here's a potential bug I found.
In turn 6 of the above replay, Accelgor moves before my Regice under Trick Room. It did not use priority, nor did I use a move with negative priority. My Regice was Assault Vest and I clicked Ice Beam. Looking at the replay, it should be obvious enough that there's absolutely no way my Trick Room Regice had more Speed than his Accelgor. Even in turn 5 I clicked Shadow Sneak but his Water Shuriken moved first. My priority move should move before his when under Trick Room.
I asked around and eventually found that if a Pokemon has 1809+ Speed, it effectively ignores Trick Room. Such a Speed stat was possible to reach with an Accelgor at +4 with Unburden activated. This was a glitch in the games that was around since like Gen 5 but I assume it was fixed in Gen 6 at least. Anyway, just wondering if the games still have this glitch or is PS not updated yet?
