I sent a fabrication bot on a long trip, and halfway there it stopped traveling in the right direction and started spinning in circles until I clicked on it and gave it new orders. Similarly, the AI commander I was fighting stopped on the edge of a cliff and jerked a little back and forth but did not retreat nor advance when fired upon; it just stood still until it was destroyed. Anyone else run into similar issues?
When I take over a moon I spam dox patrols to stop invasions. Sometimes they spin on the spot in cute little circles.
Long trips tend to be pretty buggy. And the Area Patrol for ground units often ends up with dancing units. However, pathfinding is being constantly improved with each update. So give it time. :-/
