Edit in Game crashing at loading screen is one of the worst things that can happen to a builder. Luckily, all is not lost when this happens. Read further to learn how you can get your world back if the worst happens.

Do Not Panic!

Nothing is more terrifying to world builders than when they load up Edit in Game, only to have it crash to desktop and cough up the message, “Sims 3 has stopped working,” before they even get a chance to do anything. The first feeling is always shock. Then comes the denial phase, where they keep reloading and reloading the world hoping against hope that it will load. But try as they might, no matter how many times they do it, they get the dreaded error message, and now they think that the world they spent months working on has been lost forever.

If you’re in this current situation, I know how you feel. But do not panic. There are ways you can get your world back. I know because I’ve been through this hell more times than I can count. So let’s try and see how you can retrieve your world if EIG crashes on load up.

Reload a Backup Folder of Your World

90% of the time when EIG crashes on loading, it’s because of something you did in between the time it started crashing and the last time it didn’t. It could’ve been the lots, roads and trees you added, a new mod you loaded or something else. Whatever the case may be, something has become corrupted in your world. So, one way to reverse the crash is to go back to an earlier version of your world. But how?

Whenever you save a world in CAW, it auto-generates several backups. These backup folders are located in the /Worlds folder inside of the /UserToolData folder. Each of the folders are time stamped so you can see when they were generated. Below are the backup folders for my world, Riverside. As you can see, one backup was made on March 11, 2018 and two backup folders were made on March 8, 2018.

To restore an older version of your world, open up one of the backup folders, and copy and paste both your world’s folder and its .world file into the UserToolData/Worlds directory. This will overwrite the current version of the world that is causing you trouble. But before you do any of that, back up your current world just in case something goes screwy or it turns out that the crashing was due to something else.

Try to Remember What You Did Last in CAW Before the Crash, Then Undo It

If you’ve saved enough times in CAW, chances are that there will be at least three backup folders for your worlds. But what if there aren’t any for you to fallback on? In that case, try to remember what you last did when you worked on your world, remove it in CAW, then see if you can’t get into EIG again. If you successfully undid whatever caused the crash, EIG will load again. I know; it sucks to undo all of that work (especially lots that you spent a lot of time on). But if losing those lots and some of the other work means retrieving a world that you put spent the better part of a year pouring your all into, it’s a small price to pay.

Reinstall CAW

As a last ditch effort, you can try uninstalling and reinstalling EIG. I say “try” because generally, crashes aren’t caused by any issues in CAW. However, anything is possible, and if you’re really desperate it wouldn’t hurt to uninstall and reinstall CAW just to see if maybe the program became buggy for whatever reason.

What if Nothing Works After All of This?

If you’ve done all the above steps and nothing works, your only option is to restore a backup of the world that you may have saved on an external or flash drive somewhere. However, it’s extremely rare for the issues of EIG crashing on load up to not be solvable using one of the steps above. So if you find that nothing is working and you never made a manual backup of your world anywhere, you’re SOL.
