Not sure if this quaifies as a bug or another case of the Wiki/Warpedia being outdated.
Under 'maritime travel' it says "A hero that looses the mount will drown at the end of your own turn. If the enemy manages to kill the mount of your hero, but not the hero itself, then you have a full turn to provide another mount to the (meanwhile immobile) hero."
The bolded part happened to me recently, i.e I attacked with a stack, all died exept the hero (who did not have waterwalk and were stranded in the water). After my opponents turn, the hero was still there undrowned.
Can heroes drown at all or is a full turn laying in the water needed, regardless of in who's turn the mount is lost?
