1 when I have resolved a glade event but still haven't hauled away the loot, are the negative effects still active?

2 At what point can I kick a worker from a production building and not lose what they were working on? I am concerned if a worker is making a product and I kick them that the raw materials are lost. And what if they have made the thing but not stored it yet? What happens then?

3 with mines. Does it matter how many ore nodes you place it on? Does that affect output and byproduct rates/occurrences?

Edit: one more question. What if I demo a building that has resources stocked in it? Are those lost or saved?

Thanks for your help.
