Opens build mode by itself

@annette_27399 Hello!  My, that's a weird one.  Since you removed your mods, try also deleting the localthumbcache.package which is in the Documents / Electronic Arts / The Sims 4 folder.  You also want to repair the game after that; exit the game, right click on the game in Origin and select Repair.  Depending on the number of packs you have, that might take a while.  After the repair is complete for all packs, open the game and see if it's working.  If so, you can try adding your mods back in a little bit at a time to test them in your game and see which one is causing the issue.  Also, check the creators' sites and make sure you have the most recent and updated versions.  Outdated mods can cause many various issues.

If you're still seeing the issue without mods, after clearing the cache and repairing the game, then come back and let us know.

Hello, thank you for your response, I did all the steps you said and it’s still happening and it glitches to the point that I have to restart my computer, I don’t know what else to do and it’s not letting me play the game in peace, please help me.

@annette_27399   Please post your computer's dxdiag -  how to post dxdiag  and attach the created txt file to the paperclip at the lower right corner of the response window.

Every time I open the game and go into a family the build mode opens by itself and it won’t even let me edit anything. I removed and mods, custom content and repaired the game but it’s still halo! I don’t know what else to do please help.

HI @annette_27399 

Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199

You won't loose anything. Just make sure to not delete any files  and make a backup.

After renaming, repair your game by right clicking on the game in Origin.

Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.

• Options.ini (or just re-set all your settings manually)
• Tray Folder
• Screenshots/Videos/Custom music
• Rest of the save games (leave out slot_00000001.save which is the autosave and no longer needed - if you still have it)
• Custom content like clothing, hair, skins, make up ....
• ConfigOverride, if you have your own configuration files.
• Mods (one by one, making sure they all still work)

The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.

Hi @crinrict, thank you for your response.

I did as you said, and after the game was reset I repaired it and began to put it in my saves file, opened the game and everything was fine so I decided to put the CC in the mods folder and started the game but, it opened the build mode again so I closed the game, removed the CC and opened the game again and it opened the build mode again... what do I do? Do I reset it again and put some CC open the game and put some more? like step by step? and try to see which CC is making my game break?

@crinrict Ok what I did was reset the game again (Without any mods or CC) I opened the game, created a new family and it opened the build mode again... So I repaired the game (took a very long time and Origin was very laggy). After I repaired the game I opened it and it went into build mode again... without any mods or CC!

@crinrict I uninstalled the game and installed it again and it worked fine, so right now I'm sorting through my CC to see what file is making my game crash.
