Trading with NPC's does not update their volume indicator

[Survivor1998]

Describe the bug

When trading with an NPC, after taking all their items, the volume indicator was still at 0.

Steps To Reproduce

1. Convince the starter NPC on the sheltered scenario to travel with you
2. Ask this NPC to trade with you
3. Take all of their items through trading
4. Notice that their volume indicator is still at 0.

Expected behavior

I expected to remove items from the NPC, and then give other items back after the available volume was updated. The item I attempted to give in the example below was a pair of boxer shorts.

Screenshots

In this screenshot I took all the NPC's stuff

In the second screenshot I attempted to give back some shorts, which doesn't work

I hope this was helpful, this is my first ever bug report and English is not my first language.

Interesting. Looks like NPCs cannot recognize when they should wear given items instead of trying to stash them into already-worn items. Which, of course, they do not have in this case.
Did you try giving the shorts via 'use this item' dialogue option? Or maybe 'hold on to this item'?

When you start trading with an NPC the volume always starts at zero even if she is wearing a container eg a duffel bag. This affects both neutral NPCs and followers. Does not affect the refugee center merchant (volume precisely 5000L).

Workaround for equipping followers:

• Use "I want you to use this item" to make sure he is wearing a backpack
• Use "Hold onto this item" to give items to the NPC
