The evt_nam_WarSpain_GBR event in 1755 Campaign.sct leads to the creation of a "Cuba Invasion Fleet" (many ships + land units). However Cuba cannot be entered. Instead, New Orleans appears as an objective. I'm not suggesting that the fleet should be renamed as to contain a clue about New Orleans - as far as I know, New Orleans was not occupied by the British during the 7-years war. However changing the name of the force to "Carribean Reinforcements" might have a less confusing effect. I have personally waited for several turns for Cuba to become enter-able, but no.
Come to think of it, maybe the bug is the other way around. Perhaps New Orleans shouldn't become an objective, but rather Cuba should, in which case the name of the force is OK, but the objective addition is bugged.
