When adding a bunch of drills next to each other, I can't use blue prints to duplicate my layout. I get some error message in 0.17 (that I didn't get in 0.16) so maybe this will help to figure out the issue.

Here's an example of what I'm experiencing.

And just to add more detail, maybe 85% of the drills can be blueprinted without issues. It's just that the 15% that remains can't be placed by construction robots for some reason.

When adding the grid with blue prints here's what happens (see the holes in the layout)
