Dragon attack.

I don't see any problems here; you can attack from multiple positions with the same result. But there were situations (usually with war machines) where, during a double attack aimed not at the side but at the top of the hex, or at the 2nd hex of the machine (this was related to the limited space for turning at the end of the field), the 2nd unit didn't take damage. I don't remember this happening with a direct attack.

I looked into it, and the problem is that the second cell of the ballista or tent is outside the battlefield, so even if the attack is supposed to hit it, it won't deal damage. If you attack by turning the head backward, this attack over two cells won't work – it will pass not through the side but through the top of the hex (at a right angle) and only hit the adjacent cell. These curved attacks are needed to deal more damage and take less in return, but they can't always be implemented.
