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.
