I played galactic warfare against and home world of the ai (4 enemy commanders). Two of the enemy commanders were already dead as on one planet I killed the third commander and before all of its units died, he activated the halleys, i clicked to destroy the immediately but 1 second later the planet already executed my planet. Obviously this has to be a bug, 1 sec , which flight path in space just takes a second to reach the next planet... (no moon) being killed by a dead commander is very frustrating!
