Haven't you already made backup with bandai namco id? When it was introduced some months ago there were free gems (x50 if I remember correctly, now not available anymore) and x100 gems for just 1.19€ (still available, it's an extremely great deal even if you're f2p and never purchase anything else), so good incentives to have a strong backup method.Hello! Could you please at least post the bypass for the newest version, so we can make sure we have our accounts backed up? There was no notice in interrupting the mod and we would greatly appreciate it. Thanks in advance!
Right now your only option is to play without mods and you need to restore your account through their website if nothing has changed in the last couple years (ONE PIECE TREASURE CRUISE - About support requests | BANDAI NAMCO Entertainment Inc. FAQ_en) and there are lots of details you need to give to confirm it's actually you (id, plvl, last used captain, last used team, last cleared quest, etc.) otherwise a random person could easily snatch the account. Your other option is to start a new (legit) account right now so you can start farm gems for the Global Anniversary sugofest at the end of the month.
