Doubling TC stack sizes for specific resources allows double the resources to be pulled out which allows them to use the increase stacks in any way they want. Players even craft TCs when out farming to condense their materials and farm more. They also condense them with the TC and place in other boxes after.

Don't use unless you want everyone exploiting this

You could try Chest Stack Multiplier. It has more logic to handle such cases.

thank you, I'm going to try it. Just was hoping I could limit it to only building resources (stone, wood, metal, and high qual) but it's better than nothing.
