I've noticed a few times now when setting up mining patches that only about half of the patch gets Power poles when using the Compact setting. As seen in the picture below, Power poles are added about three deep, but then suddenly stop and the back half of the patch has no power. It's not a huge issue since I can add them in manually easily enough, but I was wondering if it was a known issue.

Not know, no. I can't seem to reproduce it on my end.
Could you attach the save file where it happens?
