Treasure chest upgrades
I have two different treasure chests for Vale, a small one where I keep all of my own personal resources and a larger one for the whole camp. There are 5 of each different resource but 6 different crystals, I built 5 sections across for crystals because the pure black kind were quite rare and had alternate uses (these were kept in their own box). Without going into two many details, the secondary use of these black crystals has all but gone from the game and now they are as common as the others so I have rejigged the layout of my boxes to make room for them. Thankfully the upper three crystal types are significantly narrow than the others so I was able to fit three rows into the space of two and the boxes remain nice and neat without significant revamping.
I also took the opportunity to put a false flaw into the bottom of the big box. They're more common but we still only end up with 20 max and they never fill the section completely.
