While organizing my inventory, I came across an interesting glitch in where you can fill a cooking pot with 5 of any type of single-slot items, as opposed to just meats collected off animals. Further, I found this storage could be improved by placing said fully loaded pot onto a stove in my inventory. With two stoves in your inventory you increase carry capacity exponentially.
I currently found that you can fill yellow storage boxes with the stoves, top the stoves off with a full pot and create a box that can hold 15 single-slot items. Using a yellow box in the yellow box with a stove taking the last two slot would, in theory, create an infinite bag of single-slot item holding.
