[1.10.2] Dupe Bug with Fancy WorkBench again..

Opened this issue 7 years ago · 16 comments

I'm on BiblioCraft 2.2.4
Okay here are the steps to how to dupe with Fancy workbench

need two Bags (example two bag of holding from extra utilities) and a book
you put the book in the book slot
now you get one of your bag and full it up with items you wish to dupe with
put the bag with item in the fancy workbench into the crafting slot then Save Recipe to blank book
take out the bag with item out of the crafting slots
load Components from inventory, make sure your loading in the Empty Bag then take out from the crafting slot exit out of the fancy workbench and boom! you duped with 2 bags full with item's

Keep in mind the last dupe with Fancy workbench you'll need the bags to stack in this case you do not need them to stack some how the items in side of the last bag got saved inside of the book and can be loaded into a empty bag

Answer 7 · 2017-07-27T05:01:25.000Z

I can't reproduce it using the original steps provided and I changed the code so the item that the item that gets moved into the crafting grid comes from your inventory and not the recipe book anymore, which is how the dupe as described here worked. So that dupe is no doubt fixed. Did you discover another dupe? How can I reproduce it?

i made a video for you explain and doing it step by step

Answer 9 · 2017-07-28T21:18:18.000Z

thanks for the video. I think I see what is happening. I'll have to put some thought into this and figure out how to fix it.

Also, you should allow to save only valid recipes (with output). I think the output slot could be checked.

For the record, this exploit also exists on 1.7.10.

@Nuchaz best way to fight back on this dupe bug i'll say is to add a item blacklist so players are unable to put bugs into fancy workbench slots

Answer 13 · 2018-02-08T21:50:59.000Z

Blacklist are a pain to manage.

Answer 14 · 2018-02-08T22:02:52.000Z

do you have any other better idea? since this issue is still here since last year xD

Answer 15 · 2018-02-09T00:03:35.000Z

This looks like a classic case of comparing items with only their id and metadata, forgetting to check NBT too.
Practically, I don't know how it's implemented, so it might go deeper in maybe the way the recipe is saved in the book, etc.

Answer 16 · 2018-02-14T23:26:24.000Z

I re-watched the video again, and I think I found a relative simple workaround that would help to bring this bug further: when you click load recipe button, refuse to load the recipe if the grid slots are not empty. This prevents overwriting the actual item with the saved one, and since the stored recipe is invalid, placing the item into the grid should not do anything. This would make the in-game usage a slightly worse but would prevent item duplication.
