I'm not being able to pillage fishing boats with carracks (no pillage button). Is this normal?

Also, after one carrack leaves the resource tile being worked, the graphics for the "fishing boats" disappear (but it is still being worked, only the graphics become invisible). Anyone else experienced this?

Thanks

:bump: Can anyone verify if this is really a bug?

Ok, forget it, I checked the XML and it's intended to work this way. :)

A normal caravel can't pillage either, so I don't think its a bug.
