When I fell into my quarry, I died of fall damage.
My Openblock's grave spawned correctly, however upon being mined by the quarry non of the items were in the output chests of my quarry.
My piping is correct and it mined everything else perfectly.
I tested this 2 more times and it didnt output my items.

Hi, OpenBlocks dev here. This is caused by this line.

On first glance, it looks needless (and even harmful) - TE is normally removed in Block.breakBlock() (called via World.setBlockToAir) and it should be available until then. So what's the story behind this commit?

I put it in both github report sections as I thought it maybe an integration bug of some sort. I didn't know which mod caused it to happen so I put it in both sections.

Is there anyway to blacklist graves from the quarry via my server's configs?
I'm not a coder in anyway so I have no idea what any of that line means or does.

i remember that i used this quarry trick a once to get my stuff back afther dying in the deep dark, it wasn't the latest BC but it did work a while back so i'm guess that was indeed inteded behaviour that is now broken

Oh, huh. I forgot to fix this in 6.3.7, apparently.
