I have found the notification log. However, this does not contain a log of attacks and defences. I use quick combat and sometimes I go, whoa, what hit me?
In my current case, it was a stealth bomber.
Is there a combat log I can sometimes have a look at when I’m confused?
As I begin my turn, I see combat text on the screen. It is difficult to read and does not stay long enough.
edit: notification log does not show my tank was attacked
Here is my tank that was bombarded by a canon.
Here is the notification log
edit 2: Notification of unit death and cause. Still missing, is what attacked my unit that did not die.
The Notification log (available from the piece of paper under the turn counter) will tell you if your unit died, and what delivered the final blow. I have been unable to locate any log of the individual damage messages that appear on screen, nor have I found any mod which allows you to see these after they have disappeared.
