@Neia, seasons in worlds are an event which can be added with some FX animations and many other things like making sure all objects outside get animated to show snow on them. However, that is not even close to what would have to be done for water like in WB to be routable and without breaking a save if that was patched in or even in an EP. It's like the road system in TS4..there isn't one. And there is no 'system' in the game to allow Sims to swim in water which is FX at the moment. ETA: I have never said developers are lying. Ever. What the dev said in the old thread where they answered questions was they would have to build a whole new terrain and it would break a save to make WB ocean< (aka FX) swimable.
