I don't know if this is the problem you are having but I had a glitch where the game thought 3 of my characters were still in a dungeon harvesting even though I had returned them to the mansion. I hit the forget location button while they still had materials to collect and the resources line stayed there not progressing.
I had to edit the save game and remove the duplicate hid from the ' "workers": [], ' line for the location in the save file.
