I always thought that the Automated drills should maintain the upright... eh... leveled position. Regardless of the slope. Otherwise they look silly and unprofessional. This little fix helps to achieve that very goal. Basically, you will have much more freedom to adjust the inclination your drill have.

PS: I didn't feel like taking a screenshot from an actual game, cause I don't have any advanced saves, so I stole a vaguely related picture from some article on Google. Sorry for that. But don't be alarmed, I got to that point, and was struggling with the automated drills positioning. That mod has a real experience behind it. :3 Maybe I'll make some screens later.

INSTALLATION

Now, if you use Copper Ore Drills mod, which has proven to be working fine, you'd want to download the Drills_Build_Fix_Copper_Drill version of the main file. Just extract the contents of the archive into your mods folder and make sure it's checked and positioned below the Copper Ore Drills mod in the launcher, so that it can overwrite some of its changes.

If you don't use the Copper Ore Drills mod, then go ahead and download the Drills_Build_Fix_Vanilla version of the main file, extract the contents of the archive into your mods folder, check it in your launcher and you're good to go.
