@aodoherty I don't think this has anything to do with patch 1.42 specifically, because sims were always able to fish in the ocean, even if they couldn't swim. Additionally, the Island Paradise interactions were added separately, with that pack, so it's not a question of missing one particular patch's data.
It's strange that you wouldn't even have the base game icon after repairing the game. Do you have any files in Installer Data at all? What's the full path to the Installer Data folder? Right-click on it and select Get Info, then copy and paste the file path that shows up under Where. You can write [username] instead of your actual username, but please leave the rest of the file path intact.
@Violetkiwigirl There's no word on a potential fix, sorry.
