when you do mine diamond_ores, it only detects a certain Y range ores instead of all ores within the chunk and often times mine around or misses the ore when auto mining, "allowOnlyExposedOres", "allowOnlyExposedOresDistance" by disabling only allow exposed ores but doesn't change anything, is there any way to make it mine more efficient through the client setting? (both in multiplayer and in singleplayer issue)

also baritone only detects the nearest 64 ores that match

iirc it actually only detects the 64 nearest ores and then filters based on settings, so if the next 64 ores are not exposed/not visible/adjacent to lava/between bedrock it fails.

mine around or misses the ore when auto mining

stop it when this happens, I would bet on the ore being exposed to lava on one side.

by disabling only allow exposed ores but doesn't change anything

wait, what's your #modified now I'm confused, allowOnlyExposedOres is a setting that prevents detection of ores that arn't exposed to air on one side.

I would guess that the y range thing is not actually an issue and the closest ores by time are just more horrizontally relevant as going up/down is a bit slower

depending on your #modified there may or may not be a setting to fix it. I would suggest trying to reset your #modified settings and seeing if issues persist
