Can't craft iron bars?

For some reason I can craft anything else in both Crafting Table, Foundry, and Forge. But for some reason after some time mass crafting Iron Bars they just stopped. When trying to craft more they try to go to but stop, and start relaxing, even when commanding them to go crate Iron Bars the forging logo shows up for a second but they do nothing, this limits on what I can do in the game and is very annoying. (I tried restarting the game, rebuilding the Foundry, moving it, replacing the task).
