I was right, it's a TGL thing, what you need is BCUT -
http://www.bcs-tng.com/portal/?q=bcsmcDownload it and use it to open up the ship plugin files then just save them, that should solve your problem!
Alternatively, find the ships' plugin files (Scripts/Custom/Ships) and find the following code:
# Uncomment these if you have TGL
Foundation.ShipDef.BreenBB.hasTGLName = 1
Foundation.ShipDef.BreenBB.hasTGLDesc = 1
# Otherwise, uncomment this and type something in:
# Foundation.ShipDef.BreenBB.desc = 'No Description Available'
and change it so it reads as follows:
# Uncomment these if you have TGL
# Foundation.ShipDef.BreenBB.hasTGLName = 1
# Foundation.ShipDef.BreenBB.hasTGLDesc = 1
# Otherwise, uncomment this and type something in:
Foundation.ShipDef.BreenBB.desc = 'No Description Available'
Either will work, it just depends on how confident you feel with scripts! I'd recommend the first option as it allows you to do a lot more with the plugin files!
EDIT:
It's just occurred to me that your Breen Ship isn't where the plugin automatically puts it...what's with that?
