The priestess ability resource harvesting is suppose to randomly spawn crafting materials at resource nodes.   It's not exactly working as intended.  It is spawning crates every turn but just at exactly 2 of my about 10-15 nodes in my kingdom.   I have guys stationed there, just because every turn I know that just those 2 nodes will spawn a crate -- not any others.   The loot that  spawned is exactly the same as well at each location (different from each other, but each locations loot is the same as before).
