underwater lots causeing loadingloop

Hello. Short sentences to work better in a translator:

I tried to build a dive lot, for the first time. I followed this guide by @Karritz. It is in english:
https://www.youtube.com/watch?v=xQYREabahSE

It is very important to follow all the steps exactly.
Tip in the video: before saving make sure lot assignment is: Diving Area. When Karritz exits to Main Menu in the video: you should quit the game. Then start it again. You need to re-enter the cheats. Diving lots need dark blue water to function. Might be hard in Barnacle Bay. (Karritz have done it though).

Other tips: Save often. Save as for backups. Quit the game all the way to desktop often. Do not stay in Build/Buy for 30 minutes in a row. Do not have lots of other programs open when building. Build in a new Sims 3 folder.

Remember to exit the cheats before playing the game. Exit them before quitting the game. To exit: write them in reverse order. Change "on" to: off. Change "true" to: false.

If you want I can write out my steps from the video by Karritz. Let me know and I will try to translate them to german. (Try :smile: )

Here is a tutorial for decorating a diving lot. Also by Karritz. Also in english:

I decided to write it out, since it is complicated.

My steps following the video by Karritz:

Make a new Sims 3 folder. (Ask if you need help with this). Karritz had a few NRaas mods in it. I am guessing: Errortrap, Overwatch. Maybe MasterController. I have none.
Graphics settings do not need to be high. I check off all gameplay options when building.

Make a new save. I chose Sunset Valley.
Enter Edit Town: exit tutorial.
Save.
Choose World Editor. Place a lot. It needs to be on dark blue water. It needs to be accessible to sims.

Bulldoze lot. By this it turns to: "No Visitors Allowed".
Change it back to: Diving Area.
