That's quite a list. I'll start i guess. Some of the questions i'll leave for more knowledgable people to answer.

1 2 and 17 all sound like battle replay bugs to me. which sucks a lot. this happens every once in a while, and the reasons are still being worked out. hopefully someone else can help you there.

3) your lab only holds 50 items. rest get wasted I think.

6) the AI isn't the smartest. when you give them gems, they get a little too excited. either script him, and only give him enough gems for his script, or just don't give him gems.

7)I don't suppose he was immortal and died then came back at your cap? or maybe he has a second form without full slots and he died and went into the next one?

8)Air magic spell seeking arrow. its easy to cast (A3) and the computer will sometimes spam it. best answer- put cheap armor on your mages.

11) horrors are neutral, and will attack randomly. the spell horror mark puts a mark on an enemy, and then the horror will attack the guy with the most horror marks. to use that spell pretty much requires a mage casting horror mark. (S1)

12) if you retreat from an assasination battle (includes horrors or seduction) you die.

13) give it to an undead sneaky guy (black servant is great) and put him in the enemys cap.

14) you cannot move more than 1 province underwater no matter what.

15) the reinvig tag will still be there, you just have to do the math.

16) were they in a battle where you had the ankh or cast life after death? starvation wouldn't cause this.
