We had a player (let's call him Bad boy Mark) on our pve server who found out and exploited the following:

Our players put mines all over the map (free standing not near a TC) and thought they were protected by the mod.
But now Mark found out that he just has to place a TC next to the mine and he has access to this mine, although it is not his.

I have this option set to true:
UseCupboard - enable to share entities if cupboard authorization, in cupboard radius

And set here "storage" on the list:
UseCupboardInclude - list of types to loot with parameter UseCupboard. Types available: storage, pickup, player, corpse, backpack, backpackplugin. The default value is recommended. Note: with "UseCupboardInclude" values: player, corpse, backpack, backpackplugin - allowing loot only when both player auth in cupboard!

And set this to false:
UseOnlyInCupboardRange - enable to use the plugin only in the coverage area of cupboard

And here it actually says that "allowing loot only when both player auth in cupboard!", so both must be authorized, but that was not true in our case, it was enough that he set up a TC and he could already loot at other mines.... Did I set something wrong?

The players were now asked to put a TC next to their mines, so we can prevent this according to tests.

Lovely greetings

If earlier this parameter "UseOnlyInCupboardRange" was "true", then the plugin worked only in the coverage area of a cupboard and, accordingly, everything that was without a cupboard was not protected.

Earlier? Does that mean now no more? Because I have this option ("UseOnlyInCupboardRange") extra set to false, so that you are always protected, not only near the cupboard.... But apparently it is enough if only one of 2 people authorizes it so that he can access the things of the other without that the owner is authorized on the cupboard when you set the option "UseCupboard" to true...do you understand what I mean, it is a bit complicated:/?

Show me your config file.
How do players set up quarries for themselves? Since the possibility of setting quarries by players has long been removed from the game. For the plugin to work, an item must have an owner. That is, it should be placed by a player and should not be equal to 0.

Oh I didn't even know that because of the mines :-D
But we have just tested it with a base. Player A set up a house with boxes without TC. Player B can not access the boxes (which is great). Player B now puts a TC next to it and now he can access the boxes without player A being authorized on the TC.
