There is a single enemy ARKYD in orbit over my planet. I had my Avenger attack it. It's attacking, and missing. Forever. I've watched it miss each shot for the last 20min. Is this normal? Any ideas? I've tried stopping it and re-attacking, still missing shots. This is against the AI. The ARKYD is just sitting there too.
This is an unfortunate bug that pops up with orbital units from time to time. Give the Avengers a move order and then tell them to attack again, that fixes that.
