December 7th - A Day of Confusion?

[Strider]

1. That's a good 'wish' for the next patch. Currently, I don't know of any way to check the aggressive setting later on.

2. The aggressive setting always reverts back to normal at the end of each turn. This is 'intended' by the developer, so that players don't have to go looking at each island to figure out their setting.

To clarify, are you saying your Pearl Harbor raid did not attack any of the battleships in port? I've never seen or heard of this happening.
As far as repeating attacks, this is a bug. I've had it happen once. I think it took something like 5 phases for the game to continue on, tho it wasn't Pearl Harbor...
