Error code still occuring

Flower01373  Ok, if you deleted the ladders and are still getting the error message when you try to enter the lot, there is one other thing you can try.  Judging from the LE, the game is seeing a ladder on the lot and not finding it.  My guess is during building the lot, you deleted a ladder at some point that the game thinks is still there i.e. invisible to the eye.  So, move the sims out.  Go to build mode from the map, save the lot to your Library, bulldoze the lot then replace it with the copy from your Library.    That usually clears issues like you're having.  If you can't enter the lot in build though, then you might have to replace the lot directly from the map screen if you already have a copy of the lot in your Library.  Doing it that way when the lot has an error may take a long time.  So, be patient and let it go on for at least 30 minutes or more.  If it doesn't finish before then; the game has run into a problem and has gone into an endless bulldozing screen which you will have to force quit.  If you can't replace the lot, that lot will not be usable anymore.  At that point, you might want to consider making a new save via New Game.

Hope this helps.

Also as an extra update, I can play with the sim perfectly fine when moving her out onto a different lot, it must be something to do with the build, but I have spent hours on it (its a large castle) and don't want to make her a new house

So I went in and deleted all the ladders on my lot, and I was finaly able to play I thought it was fixed but then I saved and exited and logged back in again to check if it REALLY was fixed and the error came up again. I deleted all the last exception files, reloaded and this is the new last exception file:

Hi Flower01373 

do you have any ladders on your lot ?

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

- Delete the ones you have
- Trigger the error again
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Uploading the file is meant for troubleshooting.

Okay, this is how I fix this problem. 

You will need the following mod for this to work MC Command Centre.

1. Go into another household
2. On the mail box right click 
3. then click MC cheats'
4. The click Sims/NPC Households Cheats
5. The click Summon sim.
6. Find the sims in the household you want to play and click on them and they will turn up at the current lot.
7. The right click the sims you want to play 
8. The hit MC Command Centre and click MC cheats.
9. There should be an option to Play this household.
10. Click and it will load you to that household.

Please let me know if that helps.

If you need a video let me know and I will do one for you and link it here
