I was testing out Sins this morning for several hours, when I noticed something a bit odd. Playing as Advent, TEC sent a titan into one of my gravity wells, after a fierce battle I was victorious, however when I zoomed away to check the status of another ongoing battle, I noticed the planet's info panel still stated that the TEC ship was there. It stayed there until the end of the game, but thankfully I didn't get any more alerts about my planet being attacked.
Just thought DEV's should take a look at that.
