So I think theres an issue with fluids. I tried it with lube, petroleum, and heavy oil. I have over 500,000 petro stored in tanks, changed the limit from a digitizing chest hooked up to a chest from 10,000, my personal default, up to 100,000 and the tanks emptied nearly completely, and only some of the petro went into quantum storage. I don't know how much, but, significantly less then what was in the tanks. I had 69k of petro in quantum storage after but there was over 500k in the tanks, and I already had a small amount in the quantum storage so I'm not really sure how much is making it into storage, buts its not all of it. And I didn't have any blueprints layed or ghosts anywhere on the map, so it wasn't crafting anything, or at least shouldn't have been.
I'm wondering if its only transferring at whatever rate its allowed to, and then just deleting the leftover before the next transfer? I don't know honestly.
