Kerbal Space Program

One cargo part is duplicated in a way that overwrites another cargo part using Kerbal and Pod inventories.

Very similar to or maybe a combination of bugs #28561 https://bugs.kerbalspaceprogram.com/issues/28561 and #28559 https://bugs.kerbalspaceprogram.com/issues/28559.

Steps to Replicate:

1) Start a new Sandbox game.
2) Make a vessel with an Mk1 pod put an EVA Fuel Cylinders in its inventory.
3) Have Kerbal have its default inventory of 1 parachute and 1 jetpack.
4) Launch vehicle.
6) EVA Kerbal.
7) Right-Click Kerbal and switch out Parachute for the Cylinders in the Pod.
8) Board the Pod.
9) Right-Click Pod and see that Parachute has apparently duplicated and overwritten Cylinders (EVAing again right now reveals that the Cylinders are still in Kerbal's inventory. Board Pod and proceed to next step)
10) Swap the places of the two Parachutes.
11) EVA Kerbal.
12) Right-Click Kerbal and confirm that Cylinders are gone, overwritten with duplicated Parachute.

This also works with other cargo parts and other pods.
