Caves
- Added special caves to Ficterra. These are large predesigned caves that can spawn underground. Special caves change their look based on the biome they spawn in. Normal caves still exist and can intersect special caves. Ore deposits spawn in special caves as well.
- New Special Cave "Lava Plume" - Open cave with a basalt spiral lava slide
- New Special Cave "Ore Pillar" - Cave with a large pillar of rare ore in the center guarded by monsters
- New Special Cave "Shallow Turns" - Series of turns and a shallow cave with loot
- New Special Cave "Ice Cave" - Open cave with large ice spikes protruding from the floor and ceiling
- New Special Cave "Pools" - Series of pools in a vertical shaft with a pond at the bottom
- New Special Cave "Hourglass" - A large hourglass shaped rock lies at the center
- New Special Cave "Stairs" - Cave with a rock column shaped like stairs
- New Special Cave "Water Caves" - Twisting underwater caves with a secret
- The Red Rock Desert biome now uses Red Rock for its deep caves instead of Stone
- The cave generation algorithm has been changed to produce smaller caves especially the deeper you get. This is to prevent the deep underground from being one large twisting confusing cave
- The cave generation algorithm now produces 'smoother' caves overall with messy details, instead of just messy caves

Fabric
- "Cotton Fabric" has been added to the game. This is made with cotton and will be used in most cotton recipes
- "Cotton Thread" has been added to the game. This thread with used to sew together Cotton Fabric into items
- "Thick Cotton Fabric" has been added to the game as a sturdier version of Cotton Fabric
- Cotton has been removed from most recipes and replaced with closest equivalent amount of Cotton Fabric. This more accurately reflects that the items are made with cloth and not just raw cotton
- We've added a Tailoring Bench to Ficterra. Here you can craft fabric and items made with fabric
- Crafting recipes that used cotton have been moved to the Tailoring Bench when applicable. This better fits some crafting recipes and remove a few from crafting on person (which is a little cluttered)
- Cotton now spawns on Harvestable Plants in the Cheery Steps and Maquis biomes. This is to balance the increased importance of cotton (for backpacks) so that you should not have to explore as far to find some

Bags and Weight
- We're changing several things involving weight and carrying capacity this patch. We are lowering the base carrying capacity but adding backpacks to the game to allow you to extend it beyond what you had before. We are also changing certain ores to have a weight. Grass, Sand, Snow, Dirt and all varieties of Stone now consistently have the same normal weight.
- The Back equipment slot has been added to Ficterra. This was added to allow for new backpack items
- The character screen now shows a back equipment slot, and the offhand slot was moved to the bottom center to stand out more
- Base carrying capacity has been lowered to 60 from 100
- "Leaf Satchel" has been added to the game. Wearing this on your back increases your carrying capacity by 25. It is made with only leaves.
- "Satchel" has been added to the game. Wearing this on your back increases your carrying capacity by 50. It is made with cloth at the tailoring bench
- "Small Backpack" has been added to the game. Wearing this on your back increases your carrying capacity by 100. It is made with cloth at the tailoring bench
- "Backpack" has been added to the game. Wearing this on your back increases your carrying capacity by 150. It is made with thick cloth at the tailoring bench
- "Large Backpack" has been added to the game. Wearing this on your back increases your carrying capacity by 200. It is made with thick cloth at the tailoring bench
- The following ores and metals have had their weight increased to 1 from 0:
- Magnetite
- Chalcopyrite
- Aluminium
- Dolomite
- Magnesium
- Rutile
- Electrum
- Titanium
- Bauxite
- Iron
- Copper
- Steel
- Gold

Other
- Offhand lights (torch/lantern) now project light closer to your body and no longer cast shadows in your hand. This makes it a lot easier to see underground and prevents your light from clipping behind walls at the cost of 'realism'
- Fixed the icon for Smelt Galena being missing
- Paintings now place much closer to walls (although they are now closer when holding them)
