Here is a funny bug for you that is fairly easy to replicate...

If you control a sea province and a land province, then send unit with seduction to seduce an enemy commander in a province along the coast, it is completely random which neighboring province the seduction unit and the new commander move to if the seduction is successful.

What this means is, there is a chance the seduction unit takes the commander underwater, where they both drown! The first time I saw this happen, I got a good laugh out of it.
