I run a harvester called a mininghelot on the US Server. It has 80 4x4x4 beams and can salvage a godawful amount in little time, so much so that the actual counter int he inventory can't keep up. I can stop salvaging and open the Inventory (pressing I) then see the minerals still counting up.
A couple things can happen:
You can drop some other non counting item on a stack that is still counting and that dropped stack will disappear forever OR
You can pick up the stack of rock or or still counting, even blocks form a space station, move them from the quickbar to the Inventory or back and get a duplicate stack. Sometimes this duplicate stack stays permanently.
