When I loaded the new version; some of the mining towers the farmland mode was on by defaut. turned it off; then after reload its back.

Yes, the auto-detect will turn any tower that has only leveling designations into farming towers. If you don't want that, you can turn off

reEnableFarmingOnLoad

in the ATDsettings.json

This should be off by default. I had already played for a good amount of time by the time that I noticed that my mining site was digging more than I wanted it to.

I will consider change to default=off in the next release.

thanks
