Every patch needs to be applied to maps that haven't been visited yet. So if your Camera bug occurs in Magnet stones, then you have to return to a savegame of Gate of Swords, before entering the Magnet stones for the first time. Otherwise the patch will not work.
I assume you have downloaded and installed the patch already so I hope returning to a previous savegame will not spoil your game-fun too much. Because once installed for every following map the patch will work - did so for everyone
