Replying to my own post. Thanks again to twallan and his great mods. I installed DebugEnabler and used the forceHUD command. Then I use ALT+Q, saved, and went to the main menu. When I reloaded everything seems fine again. My interface is there and none of my sims are missing. Woohoo!

Another problem has seemed to crop up. My floor up and down buttons don't work properly and neither does pushing page up/page down. Sometimes it skips tot he highest or lowest floor or goes more than one floor at a time. Sometimes they don't work at all. I noticed this problem before, but it seemed minor and sometimes when my mouse batteries get low it start to multiple click. the keyboard buttons not acting properly is new though.

1. Which game(s) do you have?
I have World Adventures, Late Night, Ambitions, Generations, Pets and Showtime and most Stuff Packs

2. What game version/patch level?
I have the Sims 3 Standard Edition. I have no patches. I do not know which one is best and how it works

3. How many sims are missing/invisible?
Several of the town's Sims would be missing

4. Do they have an icon or not?
-

5. Do you have any UI issues?
No

6. Were the sims traveling?

7. How many traveling?
One

8. How are all travellers related?

9. Which country are the sims in?
My sim can go home after an adventure, e.g Egypt, but cannot go back to Egypt a second time. The game goes into Egypt, to the last place I was before returning home, but the sim would not appear.

10. How many days?
I have tried three and five (I think)

11. Did the sim(s) return via the phone prematurely or only when the vacation was over?
When the vacation was over

12. Returning together or separate?
-

13. Are you using SuperComputer Twallan's MasterController+Overwatch+DebugEnabler or AwesomeMod?
None of the above.

14. Are you using EA Story Progression, Twallan's Story Progression, or Awesome Story?
None of the above.

15. When did the issue start?
It started after I installed Pets.

16. What were your sims doing?
My sim does not disappear, the town's sims would disappear with their house.

17. What things have you tried
I have un-installed and then re-installed all the games a couple of times. Re-installed Windows.

18. What worked?
Nothing, as the same problem would start again.

19. What didn't work?
They same problem re-occurs over and over again.

20. Anything else you would like to add?[/pre]
The town's houses and shop and bars, library etc. would disappear as well

MonkeyS, you say you have never patched the game? How long have you had the game? Are the lots that are disappearing just becoming empty or are they turning into blue patches where the lots should be?
I would highly recommend patching your game. Open the launcher and then go to the Updates tab at the bottom. This should provide you with the patch you need to get your game up to date.

1. Which game(s) do you have?
Base game, World Adventures, Ambitions, Late Night, Generations, Pets, and just installed Showtime

2. What game version/patch level?
1.38

3. How many sims are missing/invisible?
1 - somewhat, only her icon in map view is missing, as is/was her work outfit. It was awkward. =P

4. Do they have an icon or not?
At the beginning, no, but resetting the lot fixed that for the most part - now it's only
that circle above your sim in map view that's blank.

5. Do you have any UI issues?
I get them a lot unless I clear the cache every time and/or reset the town often.

6. Were the sims traveling?
No

7. How many traveling?
N/A

8. How are all travellers related?
N/A

9. Which country are the sims in?
N/A

10. How many days?
N/A

11. Did the sim(s) return via the phone prematurely or only when the vacation was over?
N/A

12. Returning together or separate?
N/A

13. Are you using SuperComputer Twallan's MasterController+Overwatch+DebugEnabler or AwesomeMod?
I am trying Twallan's DebugEnabler tonight, but I've be using MasterController and Overwatch for some time now.

14. Are you using EA Story Progression, Twallan's Story Progression, or Awesome Story?
I was using EA's Story Progression, but I just switched to Twallan's last night to try and fix my issues.

15. When did the issue start?
I've been getting some annoying issues for months, but it just got much worse a couple nights ago.

16. What were your sims doing?
She hopped out of the shower, completely nude in her missing work outfit. I stupidly saved and exited the game. The next day when I started the save, I had UI issues galore.

17. What things have you tried
Error Trap mod: other users have reported this has helped them if they let the game run past its auto-cleanup time at 3am Sim Time, and
Overwatch mod: proven effective with removing items during gameplay which can cause lag and other issues.
Refresh/Delete the Cache File
Traveler mod: to help prevent missing Sims upon Arrival or missing UI issues.
Master Controller mod: click on a Sim, Nraas > MasterController > Household > ResetLot
Debug Enabler mod:
click on a Sim (or City Hall), Nraas > DebugEnabler > Option:Sim (if Sim is clicked) > Fix Invisible Sims
open cheat console (Ctrl+Shift+C) and enter "forceHud" (requires "testingcheatsenabled true" first)

18. What worked?
All helped - but Debug Enabler's forceHud, while seeming to be a fix, changed every hair/makeup/outfit combo I gave her - the career category was no longer there, which upset me so I exited without saving.

19. What didn't work?
All helped - but fix invisible sims and forceHud, while seeming to fix everything, caused more problems.

20. Anything else you would like to add?
My powerhouse computer had lately been BSODing quite frequently, so I wonder if that somehow is related to my game problems. For the life of me, I can't seem to find the cause of the BSODs.
