In 10.0.0.29 (experimental) in the Conflict mode, the notification that a base is under attack appears and it also starts to blink on the map (at least usually).
But the blinking disappears quickly, despite the base still being captured by the enemy.

So now there is no way of knowing (from the map) whether the attack has been stopped or the base is still being captured.
The only way to find out (if there's no one else around to give info) is to travel to the base and see if the progress bar appears. This is especially annoying now that the capturing can take over a minute in a built up base.
I assume this is not intended.
