Update of me losing all my items after trying to cheat myself 1 item:
I had Pokemon Violet Ver 1.0.1 and upgraded it to 3.0.1 and I did upgrade it mostly hoping that it would fix all my items disappearing and it did.
Hello. I'm new to the website and "cheats". I honestly just wanted to add an item I didn't have and idk what happened but because of that I have now lost all items but one, inculding key items. I did make a back up (in another folder) and used that to see if that would fix it, but didn't. Idk...
