Add a Wharf for the Hatikvah faction to buy pirate ships, which worked for V2.60 and earlier, but in the new version v3.0 beta 2 has stopped working and I can not know why?

Summarizing, these are the files that I modified in:
\libraries
-constructionplans
-god
-stationgroups
-stations
My question is if I have to modify any other file ?, so that I reappear my Wharf for Hatikvah....
