Have you encountered this problem?

I *think* I read somewhere when AIAndy mentioned that he was having problems with wisps not mining gold when the expansion is destroyed but then rebuilt. Have you come up with a solution?

I beleive this issue dosn't exist anymore. The wisp harvesting script should be taking care of that.

Yes that was a issue me and AIAndy solved long ago it havent existed for years.

How did you solve them?

Have a look at the WISP_CHECK job

It in a general sense force orders nearest wisps to harvest in a mine if its empty.

Eheh, I think my solution so far is similar to yours. Thought that there will be a better solution than just "patching," but well that's ok.
