@rebekula Sorry for the delay - I did additional testing but was still never able to generate a pool with your issue. I notice that you have additional pools in your Gallery - did you create any of them after the problem pool? Did you experience the problem again with any of them? I'm going to go ahead and add the transparent pool walls in Gallery/Library portion of this issue to our list. We still need to figure out how to reproduce the floating objects issue.
I've been able to create some new pools without issues on different lots in other worlds (such as Willow Creek), but I'm still having problems creating pools in other areas, like the Creek Corner Cove lot in Strangerville. I'm still not using any terrain manipulation when I build and always use the custom pool tool.
