AI amphibious assault from non-amphibious units

[auldian]

I've had this occur twice, both times it was Julius Caesar. The troop vessel was never visible during combat. I sent another vessel to intercept it after the incident.

A transport vessel (I've seen galleon and transport) containing non-amphibious units attack a coastal city or land-placed units. The attacking units are cavalry, grenadier, riflemen, etc. There was a damaged unit (withdrawn cavalry) aboard the fleeing transport I was able to check; no amphibious promotion.

Units may attack from the coast without the promotion. However there is a penalty

Amphibous removes this penalty

I didn't realize that. Thank you.
