Lots/Sims won't load

@gemjasmine  This happens occasionally and is a sign of save corruption, although it can sometimes be fixed.  Please start by deleting the five cache files in your Sims 3 user data folder (the one in Documents\Electronic Arts).  These files should be deleted regularly anyway; while troubleshooting, delete them every time you quit.  For reference, they are:

• CASPartCache.package
• compositorCache.package
• scriptCache.package
• simCompositorCache.package
• socialCache.package

Try to play again, and see whether the problem recurs.  If you want to save, use "save as" to rename the save, so you'll still have the original as backup.  If the lot fails to load again, quit without saving, delete the cache files again, reload, then go to Edit Town, evict your sims, and place them back in their house.  They'll keep their jobs and relationships but lose their promised wishes and opportunities.  Afterwards, let the game clock run for a couple in-game minutes, "save as," quit, reload, and see if you can play forward without any issues.  Let me know either way.

@puzzlezaddict I always clear my cache after every game. The problem's always still there. And when the game starts to fail to load, I can't save it. It just says "saving" for hours until I force quit the game. 

I tried the evict method and that didn't work either. It's always the same thing. The game loads up fine and I can play for a few minutes, and then all of a sudden my sims would freeze (time would go on as this happens). If I move my camera away from my sims/lot to check out another lot, the other lot won't load and, when I come back to my home lot, that one won't load either and my sims are now invisible. 

@puzzlezaddict I did what you suggested and ran a clean save and the problem didn't show up! So, I guessed that it was a mod causing the problem. I took out the game-changing mods, except for Nraas mods since I know those are pretty much harmless, and the issue hasn't shown up. I'm too lazy to figure out which mod it was, so for anyone having the same problem, it was either Buzz's Moar Interactions, Consort's Age mod, or SClub's EA Eyelash Removal mods.

@gemjasmine  For what it's worth, Buzzler's Moar Interactions and Consort's Age mod are widely used by people (including some NRaas people) who know what they're doing and would notice if either one corrupted their games.  So it's probably fine to put them both back in.  The age mod does take extra resources to run though, at least while it's updating the looks of the affected sims.

I am having the legit same problem for the past 7 months now, I dont think its the blue lot issue because Ive already tested all my cc multiple times. I can load in a game and be fine for either 3 mins or 30ish until the blue lot starts/sims interactions stop everything stops but time keeps moving basically forcing me to shut the game down. Its annoying and ruining the game for me because I obviously not gonna save the game when its broken.. Its hard to test the game because ive had days where it doesnt show up all day and I think I fixed it but then lol just kidding it shows up again... like seriously I just wanna play my game. 

Also I dont have any of the mods you said was corrupting it so idk all the mods I have are from big creators so I am confused

@brookangel  Please test a new save and let me know whether this still happens.  If you don't want to play a new save forward, you can let it run in the background while you do something else; just make sure to click through any pop-ups that would otherwise pause the game.

Please also run a dxdiag and attach it to a post.

Sure thing Ill do that and let you know, I do have a question. I did test my cc a long time ago and I did have stuff that was corrupted Txtcs and removed then. But I still get the glitch. I never save when this bug appears because why would I. I just reload game and go back into the save until it happens again. The reason im unsure if its blue lotting or not is because it happens randomly throughout gameplay. And its not just the lots but sims will semi disappear, cant command them to do anything everything kinda stops and sits there as the time keeps going. People are very vague when they say blue lot save files cant be saved. Do they mean cant be saved once you actually save it while its in the blue lot state? Or just the save file in general even if you remove it theyll keep reappearing at random. Cause its not like I get them as soon as I open the game. It varies and is random. I have moved out my mods folder and played for 30 minutes and it didnt show. I have turned my launcher cc off for 30 minutes and it didnt show. The only lots I have downloaded with CC are from PralineSims on TSR. Like is it even a CC thing at this point? I wouldnt really know because it happens at complete random testing it is very hard to do. Ill link some photos of the glitch if I can get it to appear

@brookangel  I would say it's not precisely a custom content issue, it's a game engine failure.  But bad custom content can make that failure much more likely, as can lower-end hardware that can't keep up with the demands Sims 3 is placing on it.

I would never save the game when it's in a state like this, but I wouldn't expect that saving progress before this happens in the current play session to be a problem.  Of course in a save where this is a recurring issue, the save itself might be corrupt, but then it's a question of whether you want to play that save forward, and if you do, you'll need to save your progress at some point.
