(Sorry, I translate via google)
In the MineProcess.java file, I found the ORE_LOCATIONS_COUNT constant. I have a problem AllowOnlyExsposedOres does not find ALL ores. Having flown to freecame, he noticed that he did not see in distant chunks. Can you somehow increase the scanning distance without rewriting the mod?

For performance reason Baritone discards all but the closest 64 ore locations. Usually that means it will consider the farther away ores once it has mined the closer ones, but due to how allowOnlyExposedOress, the unreachable blacklist and pruning implausible ores work it can happen that the closest 64 ores are all invalid, in which case Baritone will fail.

If that's a problem for you, you have to compile Baritone yourself with ORE_LOCATIONS_COUNT set to a higher value.
EDIT: ORE_LOCATIONS_COUNT has been replaced by the mineMaxOreLocationsCount setting.
