Got a funny one today. Made several attempts to reproduce it, but while I have concrete steps, I was unable to manage it- it kept resetting, like it's supposed to. I suspect the trigger may have been frame-perfect.

The arm snapped back into the standby position when I issued it another command, but it did not reset when it completed the movement command that started the glitch and picked its own path back to the mine.
Update 4.2 | v0.8.6c (b612)
Reproduction:
The excavator picked a spot to mine, traveled, then started rotating and extending its arm to pick up terrain. During this motion, I paused the game, issued a move order, and resumed the game. Later attempts were either too early (arm reset into position) or too late (terrain damaged, arm reset). Having a large angle between its neutral cab rotation and the one necessary to dig might be an important ingredient.
