Mod name: Ore Harvester

Description

Mining Veins of 2 Block tall ores don't yield any result. Blocks get destroyed, but items aren't dropped

I believe this was because the drop would go into the block above, which has been fixed in version 1.3 of Ore Harvester. Thanks for opening the issue and giving the mod a try!
