I'm playing with the Vanilla save in this world and I'm having tons of fun! Thanks so much for making this updated Sunset Valley. It's already one of my faves
A few things I noticed:
My sims float above waterlevel when swimming or snorkeling on dive lots. The scuba buoy also floats above water level, which is causing it.
I followed this to fix it for myself:
https://simsvip.com/sims-3-island-paradise-guide/creating-dive-lots/Basically lowering the level under the scuba buoy and then levelling the terrain to that level. Grab the scuba buoy again and let it sit on the water instead of floating above it. Then use flatten lot so that the lot is on sea level again.
My sims don't float anymore now, but the downside is that it was a lot of work (some objects need to be moved or else the lot can't be flattened there) and the diving lots don't look as pretty as they used to, because the lot is completely flat now. I can make it uneven again of course, but I'm not looking forward to that tbh
Maybe this can be fixed in the new update? I would love that and wouldn't hesitate to start a new game in this world, I really like it!
Another thing I noticed: sims got stuck under the front porch in the Hart household. Super strange. It kept happening until I bulldozed their house and gave them a new one.
