[OPEN] Pools on elevated terrain are inaccessible by Sims

@annabelrichison Can I ask a few questions for  clarification?

• Do you see this issue in other lots in the game? 
• If you try in a different game save do you see the issue?
• Is your game fully updated?

  How to run a game repair:

  • Open Origin, click ‘Game Library’ then right-click Sims 4 > Repair Game
  • If you’re on PC, make sure to let it run until it has completed all repairs (it will do the base game first, then run through each of your DLCs (Expansion Packs, Game Packs and Stuff Packs).
  • If you’re on Mac, the repair in Origin will only repair your base game. Learn why and how to repair your DLCs (Expansion Packs, Game Packs and Stuff Packs) at this link: https://bluebellflora.com/2020/06/17/repairing-sims-4-packs-in-origin/Have you tried a game repair (click spoiler tag)?
• Do you have Mods/CC? If you do, or if you had them in the past, please try the following to see if it helps (click spoiler tag):

  Do you have any Mods or CC? If so, please move your Mods folder from your "The Sims 4" folder [Documents > Electronic Arts > The Sims 4] to your desktop (save it for reference) and delete the localthumbcache.package file in your “The Sims 4” folder. Then check in a new game save to see if this issue is still occurring. If the issue is gone, please re-add the Mods/CC one at a time until you find the one causing the issue. If you have a lot of Mods/CC you can use the 50/50 method.
• Would you be willing to share your lot to the gallery so I could test it in my game? If so, please share the lot to the gallery then add a comment to this thread letting me know the exact name of the lot )you could call it something like 'pool test'). Please also let me know if your User ID in the gallery is different than it is here.
