AI recycling sunk ships on battle of atlantic mode
 

I downloaded Atlantic Fleet for my mobile device and have run into the same ship twice on multiple occasions in the Battle of Atlantic game mode.

I do not have the game set to allow the AI to recycle ships (I have the game options set to default) and I am certain that I'm facing the same ship and not two different ships with the same name. In one playthrough I sunk HMS Nelson twice (I sunk three nelson class battleships total, only two were made). On my latest campaign I sunk the LM class destroyer HMS Guhrka twice and have not encountered the Tribal Class Destroyer of the same name.

I'm not certain if this is a user error or an iasue that will need to patched in an app update. Any help would be appreciated
