Hello, I grabbed the Flash HM and logged off shortly after. when I logged back into the game my lvl (i think) 37 venusaur with a leftovers had turned back into a level 5 bulbasaur with a sitrus berry. unsure how it happened as I had logged off and on several times since I got the bulbasaur at the beginning but if it helps he knew razor leaf vine whip leech seed headbutt the bulbasaur has a kanto ID of 52528825 though I am unsure if that would have changed if there is any way to restore it I would appreciate it as it was 1 of the only 2 I actually levelled so far and i'm not sure I can progress much without it Silver Server
