Ghost Ships - Bug?

Any ideas what may be going on here?
1, Clearly, I have 5 ships in a fleet in St. Martins.

Why does it not say the fleet is 'Available"?
2. Click to the St Martins' plunder-board - there's Teach with his fancy SOTLs ..

3. I click 'Assault" -

Huh?
What be?
4. Rechecking my fleets I find this also:
ShipsGalora also has no sign of being "Avaiabie" ..
All my other ships are either fishing or available.
Do St Martin's and Aiora now have the facility to make ships that enter their harbours invisible and hide them from their captains?
(Sounds like a handy new voodoo card
)
Seriously tho .. does anyone know whats going on here please?
