Well, I've been crippled by what I can only assume is a bug.
My immortal pretender died trying to take my first indie province. In my dominion before, during and after the battle. The battle results show 0 commanders killed, which would be normal for an immortal. But, no pretender in my capital. I believe "Call God" is now an option for my priestess (I'm not at the computer so I can't check.)
I poked around a bit here and it looks like the reincarnation bug, so if anyone got a character with unexpected magic paths I want him back
I'm not sure what to say. Later in the game this wouldn't be such a big deal. I'd just turn my priestesses to calling him back. Now, though it's about 5 turns of buying priestesses instead of researchers, at best half the expansion. If it was my fault I'd just suck it up, but to be hurt that bad by a bug really sucks.
