Lvl 1 quarrry not producing anything - AU Survival

I placed a level 1 quarry yesterday near my base, but didn't run it for lack of LG. Today, I finally got it running, but it is producing nothing. Also, when you check on the low grade in the quarry, it instantly adds it back into your inventory. I thought this might be a jpipe issue, so I removed them from collecting ore, and it stayed the same - no output.

As far as I have seen, the public quarries are working fine, and this is just a private one. Also, yesterday, a player complained that he could not upgrade his quarry. I told him to write a ticket, but unsure if he did. Same server - AU Survival.
