So I just disassembled my canola farm (9 presses, 30 barrels and 48 generators)
And though the generators can be emptied (from a previous issue) by placing them in crafting table, it seems impossible for the press or the fermenting barrels. This in turn makes them un-stackable.
Is it possible to drain them in any way? (remaining un-fermented canola oil in barrels, power in press)
