You mentioned in the previous issue that you can do this with all slimefun gui machines and I did mention that this is a very important factor here as that is the difference between this being a slimefun issue and an infinity expansion issue. Please edit the detail of the call the machines you have been able to do this with and then amend the title of the issue as appropriate. If this call is left as-is without this the next person to come along may be likely to just close it

The thing is that I am not sure if it happens only with storages from infinity expansion (barrels) cause its not that easy to do it in the same time with other guy, my thoughts are it may happen with blocks that are able to hold items inside them after break.

[Sefiraat]

That differentiation is very important here as it’s the difference between this issue belonging on this repo or belonging to another repo. For now I will give the benefit of the doubt as you have said you achieved the same results on other slimefun machines, if you could please test and confirm this (I would but I’m not near my machine for a while) and if it is confirmed we can change the description and title to something more suitable, otherwise it’s needs to be redirected. Thanks

[EagL3-GIT]

There is no such a machine in slmefun gui which stores items inside after break up, so its not even possible to test it on "default" slimefun

Anyways this is a known bug for a long time if u check old posts: https://github.com/Mooy1/InfinityExpansion/issues/114

Hi Sefi,

Is there any update about this bug? I tested this bug with other storages for you but no the infinity expansion storage was the only one who made me dupe. This together with the other SF dupe makes it rain abuse on the servers from keys to cosmetics.

I tried it with the Quantum storage but no effect. If there is anything I can do regarding testing to help let me know.

Actually poke, there are multiple dupes on your server and not only that but there are some very poorly configured plugins and permissions so maybe you should get started on fixing those first.

I know there are multiple with backpacks/storages/shulkers and all kinds of crazy silly stuff (danktech too) but this one is far the most used one when we bust people on duping sadly.

Imo there is no way to prevent any abuse anyway, from hacks to duping but thats a different discussion. This one is far most used (sadly) probs because its so "cheap" to do so.

Fun fact: This addon isn't responsible for the dupe alone, it's the combination of this addon which another one that you (and some others in the issues sections) use. You can prevent this dupe just by changing values in configs. Good luck on figuring this out, adiós
