I'm building Ares' fortress and stuck at 90%. It says it will require additional 4 slabs of marbles and 2 sculptures. I have lots of them on my stocks, but they don't finish the production. I tried everything, put stockmarkets nearby but nothing works. I need your help!
Off the top of my head:
1) Make sure you didn't halt construction by mistake
2) Make sure you are not stockpilling the materials
3) Make sure you have Artisans' Guild and it has workers
4) Make sure there is road between Sanctuary and the needed materials.
If all of above is not fixing your problem try to make sure that stockyard that has the materials has them on accept not get.
