Mining stacker doesn't release certain materials.
Created by: Feriath
If a miner finds mythril (by digging the wrong stone and causing all archaeologists everywhere to cringe suddenly), then puts it on the conveyor belt so it ends up in the stacking machine, the stacking machine will not release it. (Tried with a mining borg, not a human. But mining borgs can release other materials from the stacker...) This also might apply to other materials.
