A few minutes before a recent crash, I equipped my Gastly with my Macho Brace. I ev trained for a bit in route 6 before the server went down.
Once the server came back up, my Pokemon had been reset to several minutes before, but my inventory was updated (or at least it was a MORE recent version of my inventory).
My macho brace disappeared into thin air, and afaik there is only the one trading npc to get it. I understand you guys say "nothing will be returned from a rollback", but what do you expect the players to do in cases like this? Pokemon can always be re-caught, but certain items can only be bought from other players.
