On US Scourge.
I mentioned this to @Death In game chat a few days ago but I don't think you understood what I was saying. For a week now I have not had to put LGF in any of the quarries. About two weeks ago on a server reboot I had what I call a admin stack. Thats where you end up with more in a stack that is normally allowed. My LGF I had in it ended up stacking to a single stack of 14K. I kept putting 5K LGF in each of the quarries each day when I cleared it out but the first slot still had the 14K stack. I eventually stopped putting LGF in it after a few days as I was getting more with Pure Tea in half an hour then what the quarry was giving me in a day. Its that time in the wipe where I wanted to save my LGF to sell off at the end of wipe. I kept checking the quarries waiting for my LGF to run out and noticed it only consumed LGF when I was in range and output was the normal amount. If I add LGF to the quarry it will consume the normal stack at normal rate, before it starts on the other stack.
Looks like something in the code where if stack is greater then 10K it consumes it at a greatly diminished amount.
