[0.93.4] (Exploit) Backpack Muling

[Dreadarm]

You can place items inside your backpack and the unequip it.
There are several problems with this as I am sure you can see.

You can fill a backpack and then place it into another backpack.
-- Example, I can fill several trader backpacks and put them inside another trader backpack

you can then unequip this pack and you no longer get any negative penalties from wearing it but you are still able to carry all the extra goods.

[Drag00ne]

true as long as you save and load when you loose everything in that backpack

[Hatsune_Neko]

there is a chance, anything you place into the backpack that you put into the other backpack, could be lost.
this has been tested before and is known.

But weight of extra items still applies, right? So overweight penalty is still there? When i'm about to sell some sabres from hungry bandits, i fill medium backpacks with them, before putting those backpacks into a bull pack, and load is still quite heavy. Not sure if any weight reduction working at this case.

[Hatsune_Neko]

do not remember if it was or not.

Backpack weight reduction is only applied when the backpack is worn. Stuffing a backpack with goods, then putting it into another backpack does not apply the weight reduction of the items in the backpack that is in the backpack. Those are -equip- bonuses only, to the total weight that is inside the backpack. The backpack that is equipped will apply the reduction of weight to the total weight of the backpack that's in it, with all the goods inside.. So if the backpack inside weighs 50kg, and there's 216kgs of goods inside that backpack, it will apply the reduction to the total weight. (50% off of 266kg is 133kg)

You can see this by placing a backpack with goods inside it in your inventory, vs while it's equipped.

Yes, you can fill a backpack with goods and put it in your inventory to also circumvent the combat penalties, but you do not get the weight reduction. There's a trade-off both ways.

Though I still think you should not be able to place backpacks that have items inside them into other backpacks.

Here's a little chart:

Say you have a 50kg backpack (backpack A) that you are wearing that applies 50% reduction to everything in it.
Inside that backpack you have another 50kg backpack (backpack B) that reduces 50% of the goods inside it.

If Backpack B has 100kg of goods inside it, but is not Equipped, it's total weight will be 150kg. Once it's equipped, it will be 100kg (50kg bp + 100/2)

If backpack B is not equipped though, it will weigh 150kg (no reduction) So placeing B in A, will have that reduction applied to the total weight of B, so long as A is equipped. Meaning that B will weigh 75kg ontop of A's 50kg.

I don't think it's a big problem. While it's not very logical (i mean putting medium bp into another medium bp, for istance, which are the same volume, and some place will still be available in a backpack a) and has some benefits, strenght limits of a character still applies. Besides, weight isn't absoulte, it's a force applied to a support or hanger, and depends greatly on the area of appliance. What i'm trying to say here is: nicely packed backpack might be fitted into another similar backpak with some weight reduction applied. Probably not 50%, but some.

[Drag00ne]

I only half way agree with you. While you can pack some things in a box and then but those things in another box and even load it in a car/plain/ship container the weight still apply for all the items you have packed.

P.S. The volume too

[JabberwockyBen]

I think an easy fix here would be a logic barrier?

Say a backpack of any kind may only be placed in another backpack if it is empty. This would make sense from a physics and weight perspective. And I know when I've sent a person to town to purchase backpacks for others, I follow this idea to load empty backpacks into their storage.

Just a thought!
