We have been hearing reports of Blight affecting all areas of Travance lately, so it is likely your crop issues are connected.
If there is talk of evil sticks, I do remember when we had to deal with those evil stick doll totem things? Courtesy of that infernal bird skinwalker? Don't know if it's the same thing making a reappearance.
The good news is, all these issues are likely connected. So once we purge the taint of blight with extreme prejudice, the farm should be safe again. Please tell your farmhands to stay safe, and we will help restore the crops after the root of the problem is handled.
