CCA Compat Fixes — v1.0.0

A compatibility datapack for the Cozy Cobble Adventures modpack. It resolves crash-causing missing-function errors, fills in absent loot tables, and stubs out broken tag references so all listed mods load cleanly together on Minecraft 1.21.1 (pack_format 48).

Required Mods

This datapack only matters if your instance includes one or more of these mods. It is harmless if a mod is absent — every override is either "required": false or a safe empty stub.

Mod	Namespace
Cobblemon	`cobblemon`
CobbledLoot	`cobbledloot`
CobbledStops	`cobbledstops`
Cobblemon City Towns	`cobblemoncitytowns`
Mega Showdown	`mega_showdown`
RCT Mod	`rctmod`
PokeLoot	`pokeloot`
201 (rewards mod)	`201`
Deeper Darker	`deeperdarker`
PTL Structures	`ptl_structures`

What It Fixes

Missing Function Stubs — `minecraft:tick` crash prevention

Three mods register functions into minecraft:tick but ship without the actual function file on 1.21.1, causing the game to log errors or crash on world load. This datapack provides no-op stub files and registers them as optional ("required": false) so the tick tag never errors.

Function	Cause
`cobbledloot:tick`	CobbledLoot 1.5 registers this but the file is absent
`cobbledstops:tick`	CobbledStops 1.1 registers this but the file is absent
`cobblemon:main`	LegendaryEncounters registers this but the file is missing

Loot Table Overrides

All overrides replace loot tables that are either missing entirely or reference items that do not exist in the current mod versions, replacing them with weighted pools of valid Cobblemon items.

`cobblemon:` sets (used by multiple mods as shared loot pools)

Table	Fix
`cobblemon:sets/any_evo_stone`	Replaced with empty table (items unavailable)
`cobblemon:sets/any_ancient_held_item`	Replaced with empty table (items unavailable)
`cobblemon:sets/any_exp_candy`	Replaced with empty table (items unavailable)
`cobblemon:sets/any_natural_heal_item`	Replaced with empty table (items unavailable)

`minecraft:` (Cobblemon's vanilla-namespace loot pools)

Table	Contents
`minecraft:loot_table/cobblemon/basic_loot`	Poké Ball, Great Ball, Ultra Ball, Premier Ball, Legend Balls
`minecraft:loot_table/cobblemon/held_item_1_loot`	Type-boosting held items (Charcoal Stick, Mystic Water, Magnet, etc.)
`minecraft:loot_table/cobblemon/held_item_2_loot`	Battle held items (gems, Life Orb, Choice items, etc.)
`minecraft:loot_table/cobblemon/apricorn_ball_loot`	Apricorn balls
`minecraft:loot_table/cobblemon/apricorn_loot`	Apricorns
`minecraft:loot_table/cobblemon/basic_loot`	Core Poké Balls
`minecraft:loot_table/cobblemon/evo_item_loot`	Evolution items
`minecraft:loot_table/cobblemon/special_ball_loot`	Specialty Poké Balls

`minecraft:loot_table/cobblemon/vitamin_loot`	Vitamins / EV training items
`minecraft:loot_table/cobblemon/x_item_loot`	X-items (X Attack, X Speed, etc.)

`cobbledloot:` (CobbledLoot chest rewards)

All four tiers replaced with valid Cobblemon held items and battle items weighted by rarity. pokeball_loot · greatball_loot · ultraball_loot · masterball_loot

`pokeloot:` (PokeLoot block rewards)

All four tiers replaced with wide pools of Cobblemon Poké Balls, medicines, berries, gems, and held items. blocks/pokeball_loot · blocks/greatball_loot · blocks/ultraball_loot · blocks/masterball_loot

`cobblemoncitytowns:` (town chest loot)

Chest loot provided for all seven towns: Pallet Town, Cherrygrove City, Floaroma Town, Lavender Town, Lentimas Town, Pacifidlog Town, and Twinleaf Town — including lab, flower, tower, mansion, and size-tiered variants.

`rctmod:` (RCT Mod trainer / generic rewards)

Trainer default — potions, Poké Balls, Revives, Rare Candy, Exp Candy XS
Trainer groups — custom loot for 40+ named trainer classes (Ace Trainer, Gym Leaders, Rivals, Elite Four, Champions, etc.)

`201:loot_table/rewards`

Premium held-item pool: gems, Choice items, Assault Vest, Rocky Helmet, Lucky Egg, Exp Share, Leftovers, Shell Bell, PP Max, Rare Candy, Ability Capsule.

Tag Stubs — crash / log-spam prevention

Tag	Fix
`deeperdarker:entity_type/sculk`	Replaced with empty list — Deeper Darker's sculk entity tag references entities absent in this modpack version
`mega_showdown:item/sparkling_stones`	Replaced with empty list — item does not exist in current Mega Showdown build
`mega_showdown:item/arceus_plates`	Explicit plate list with `"replace": true` to override any broken defaults
`mega_showdown:item/genesect_drives`	Tag stub
`mega_showdown:item/oricorio_nectars`	Tag stub
`mega_showdown:item/silvally_memories`	Tag stub
`ptl_structures:worldgen/structure/kyurem_cave`	Empty stub — structure tag referenced before structure is registered

Miscellaneous

cobblemon:dexes/mega_z — Empty Pokédex definition stub (sortOrder: 99) to satisfy a registration reference from Mega Showdown without polluting the in-game dex UI.
mega_showdown:recipe/legend_plate — Crafting recipe: surround a Nether Star with 8 Arceus Plates to craft the Legend Plate.
