[FIXED] Breeding issues resolved
Animals like the Plastemmoth were previously unable to give birth due to incorrect adult age settings. This has now been fixed, and they will properly reproduce once they reach maturity.

[FIXED] Furpotamus caravan carry functionality
The Furpotamus was not increasing caravan capacity as expected. This has been corrected and it now properly functions as a pack animal, contributing to hauling weight during travel.

[ADDED] New visual when Furpotamus is carrying items
A custom texture was added to show when the Furpotamus is loaded with supplies in a caravan. This improves visual clarity and adds immersion during travel scenes.

Update: Biome & Spawn Balancing + Lore Pass 8/2/2025 4:10:23 AM.

[ADDED] Added lore-rich origin paragraphs for all creatures: Scarodon, Raptorkhan, Deermoss, Duskhorn, Furpotamus, and Plastemmoth. These segments appear at the end of each animal's description and provide in-universe explanations for how these species came to exist or adapt on RimWorlds, referencing abandoned gene projects, terraforming experiments, orbital debris, and ancient tribal myths.

[REBALANCE] Rebalanced wildBiomes spawn rates across all custom animals. The goal was to keep them distributed across multiple biomes while reducing their overall frequency. Spawn weights were lowered per biome, especially in colder regions, to avoid overcrowding and better reflect the rare, mythic tone intended for the mod.

[REBALANCE] Adjusted ecoSystemWeight values to better represent each creature’s ecological footprint. Scarodon, for example, had a relatively low value which allowed too many to coexist at once. We moderately increased weights to keep animals present but prevent them from overwhelming the ecosystem.

[REBALANCE] Set Scarodon wildGroupSize to 1–1 to reinforce its role as a solitary apex predator. This prevents group spawns, fits its intended lore, and resolves issues where too many would appear in dev mode tests.

[FIXED] Corrected a texture loading issue for the Scarodon corpse (Scarodon_Corpse.png). File path and definition were cleaned up to ensure textures load properly on death and butchering.

[FIXED] Resolved definition stacking issues caused by duplicate entries across animal XMLs. Some creatures were appearing more frequently than intended due to improperly handled patches or overlapping defs. These conflicts have now been fixed.

[FIXED] Fixed item stack limits for special resources like MegaBone, Mossmire Draught, and Emberheart Slice. These items were missing proper stack size values, causing issues with storage, hauling, and interaction with shelves and stockpiles.

[FIXED] Updated the MegaBone item. This resource now has a distinct identity compared to the Dark Ages Giant Bone. MegaBone is heavier, slightly more valuable, and is planned to serve as the base material for tribal-tier weapons and tools in future updates. It plays a key role in differentiating this mod by offering unique crafting potential.

[FIXED] Rebalanced Mossmire Draught and Emberheart Slice. Previously, their effects were inconsistently triggered and linked to incorrect thoughts. They now apply their intended Hediffs properly, with correct cooldowns and stack behavior. Mossmire Draught will continue to evolve as a mystical healing brew with potential for addiction. Emberheart Slice remains a potent, combat-focused stimulant meant for emergencies — not casual use.

[ADDED] All animal skeletons now have custom textures. This enhances visual consistency after corpse decomposition, reinforces each creature’s identity even in death, and adds immersion when exploring or scavenging in the field.
