Too late bro, they banned me, although I tried a different method. I edit the savefile to get unlimited bundle buy, then bought them with lucky patcher so it free. First I find someone else savefile that already buy that limited one time bundle, get their file, edit with notepad, copy the third line, then paste that to my save file third line. After that, just enter the game, buy that bundle via lucky patcher so it's free, exit the game, relaunch and the game will said "receive ***** pack". Just repeatedly buy the bundle. However crab war has really good protection so they banned me right at that evening. But it just a decoy account so I couldn't care less.
