Phantom leaders?
I played as Castile, starting 1492, difficulty normal.
After annexing Granada I sailed to the new world (Exploration was very easy, almost no problem). Built up a colonial city and with a recruited conquistador scouted the Aztec lands. Looks like it's possible to scout the entire country if you land on the first unknown territory from a ship.
So, war time. Initially only the conquistador with 2k knights and 2k infantry, I didn't fare so well so I shipped another 4k from the continent.
At some point in the war, I wanted to get even more troops from the continent since the war wasn't faring too well. So i sent my fleet back, and, having not taken them into a port in a long time, the whole fleet promptly sank in the middle of the Atlantic. Serves me right for being stupid
However, somehow Columbus swam to the shore and found his way back to the leader pool.
Likewise, when I fought the Maya, their chief-become-general Can Ek I had shock 5 and kicked my armies badly a few times. Finally I thought I managed to get his stack, but Can Ek I soon reappeared in the helm of another stack. I thought it was an oversight from me, but after I was certain for the third time that I had got him and he still came back, the only conclusion is that the leaders survive stack annihilation. And the 'luck' of Columbus is quite good evidence on the issue, too.
This sounds really really bad and a drastic 'dumbing-down' of strategical warfare, removing the biggest risk to leaders. In EU2 it was the random battle death of leaders that sucked, not the stack annihilation death. Is this a bug or a feature? If a feature, is there a percentage chance for the leader to survive or is it always?
