The Building Block in quarry mode dropx massive amounts of XP. This is very annoying, bacause it slows my client down until it reaches 1fps.
Is there a config option to disable this? Or can you add one?

Minecraft 1.12.2, newest forge, newest RF tools

Hmm, pretty hard... Not sure how I would go about doing that. Have to think about it

Oh, I thought you were dropping the XP, because they drop out of your machine

maybe add an internal XP buffer (mob_grinding_utils can store XP for example). But your internal XP buffer can be voided

No, the drops are from the blocks that are being harvested and the problem is that when I harvest a block these XP orbs are generated out of my control

A workaround would be to destroy all EntityXPOrb in a certain area
