I made a new one because the last one got trashed, I have sold this once and it is still working as of today. I have continued to use this and have not been banned + maxed out my collection. If you spend an hour doing this, you can probably do around 200-250k items "obtained" (in perspective, u would unlock emerald armor which is 100k emeralds collected normally and another item of choice) I have discovered a new version of this collection bug where in a short period of time you can unlock any craft you may need! I have used this myself and unlocked all of mining and combat crafts in a day using this glitch. If you are interested in buying it lmk! This is a use at your own risk thing, but I have used the previous glitch and this one and still am unbanned!
