After I finished watching a recording in the Battle Arena, my pokemon’s held items disappeared. They are not in my bag or on any other pokemon. Is this a glitch/bug? This wouldn’t be a big deal for me, if I wasn’t missing my flygonite. Is there anyway I can go back in my save states to recover my items before I watched that recording?
It’s just a bug. Wait 'till a future patch that’ll fix it.
So my Flygonite is forever gone then?
You can try to revert to a backup.
Load a backup save, the default save file of the first save slot is Game.rxdata and backup saves are named something along the lines of Save_0_Backup_1.rxdata. Simply delete (or rather, move away) your current save file, rename the backup of your choice to Game.rxdata and keep playing. The backups update every time you save.
Tried going back, still couldn’t recover my Flygonite
I have an alt save where I could get you a Flygonite. Do you want that?
