Here's a basic diagnostic:
1) Your dwarves are idle
2)Your dwarves have ordesr they should be carrying out
3)Assuming the game is functioning properly we must then look at the things they need to carry out that order:
PATHING: Can your dwarves freely path to and from the subject of the order? ( in this case, stone)
Can they path from the stone to the stone's destination?
COMPATAIBILITY: do they have the appropriate tools for the job(unless you had a most CURIOUS accident and all your dwarves are missing hands I think we can assume yes)
Is the subject compatable with the location(sub-breaks into: Is the stockpile full? Okay. Now go to d,b,H and do it over the stockpile. How about now? Still no? Is this stone type permitted in the stockpile?
My guess is that you either have an invalid path, through building or locking a door, or that the stockpile and the stone aren't compatible.
Went down each item to no luck. pathing isn;t an issue, I made a fresh stone stockpile right Next to one of my quarries, no one moved.
Iv'e made 'fresh' stockpiles, every stone on the list is permitted, there shouldn;t be any problems there.
Finally, stockpiles that have been around from the begging, that have been refilled over and over, are no empty. I havnt touched them or change them in any way. Either something in the game is wrong, or somehow Ive "turned off" stone gathering on everyone.
