When trying to conquer and raze some outposts the AI put near me that overlapped a Clambercoil Dragon, to try to avoid waking the Clambercoil dragon near my cities, the CD woke and attacked my small stack. They were not in a position to possibly defeat the Clambercoil dragon, so I Auto-resolved to get the pain over with. They won. I couldn't believe it so I took a look at the log. While my 3 remaining units made around 40 attacks to whittle it down, the Clambercoil dragon made a single firebreath attack at the beginning the terminated the forth.

It seems I can't copy/paste from the battle log, so I'll include a dropbox link to the save game and debug log in case you want to try to replicate. Note that mods are disabled for this game.
