Drone attack bug?

[DavidG]

I just played a turn a multi simultaneous game and notice what appears to be an bug. A single drone attacked my planet that had 6 WP's on it. Each had 1 PDC and 2 PPBs. The drone hit?! From the combat review it appears that only one on the wp's fired. Is this a know bug? (all the WP's were the same class)

There's a known bug that drones don't consistently trigger PDC fire; it's supposedly fixed in the upcoming patch.
