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).
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.

minecraft:tick crash preventionThree 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 |
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.
