Sync

MonsterDB includes full server synchronization support so all clients stay consistent with the server's configuration.

Step	Description
Game Load	Plugin starts and reads all files from the `Import` folder
Server	Loads imported files, creates clones, and applies all updates
Client	Waits for files from the server, then creates clones and applies updates
FileWatcher	If enabled, any changes made on the server are automatically sent to all connected clients

RRR

To convert RRR.json files into MDB.yml files, install https://thunderstore.io/c/valheim/p/ValheimModding/JsonDotNET/ to gain access to command: monsterdb rrr which will look for files within folder RRR at BepInEx/config/MonsterDB/RRR

RRR Converter was designed to parse both RRR.json and DropThat.cfg to coalesce into MDB.yml
