Troubleshooting

Symptom	Cause	Fix
Edited the config, nothing changed	Config values are cached until reload	/raidlegendaryrate reload
Per-dimension rate ignored	Dimension id without namespace or misspelled	Use the full id, for example pixelmon:ultra_space
Legendary raids still common in Ultra Space	Rolls per hour, not per roll, is the issue	Lower Ultra Space's override or turn on player scaling; check with simulate
Ultra Beasts banned in one dimension	Second value set to 0.0	Leave it out to inherit the global share
Mod seems to do nothing	raid-have-legendaries: false in Pixelmon, or enabled = false	Check both

Boot line that shows it loaded: Raid legendary rate normaliser registered on Pixelmon.EVENT_BUS. A reload logs config reloaded from <file> (<n> change(s)).
