Drills broken in 22.214.171.1249 on linux
After updating to prerelease build 1569 Drill-O Matic drills give the message "no ground contact" unless they are placed at right angles.
How to reproduce:
Create a ship with a Drill-O Matic part in any normal layout.
Land the ship on a body (tried minimus and Kerbin)
Extend the drill
If the drill is at right angles (as in the screen shots) it will extend correctly.
