I would LOVE if someone could explain this to me. I own all of the EA towns, one from the exchange, Union Cove, and all of the expansion packs. This leaves me with a lot of towns. However, I get crashing in all of them except Sunset Valley and Riverview. I haven't experimented with Twinbrook or Barnacle Bay yet, but these ones definitely crash: Hidden Valley, Union Cove, Appaloosa Plains, Starlight Shores, and Lunar Lakes. It crashes after anywhere from 30 minutes to a few hours.
I've been using the crash diagnostic tool from Mod the Sims to try and narrow down all of my crashes. I've had a few different ones, but they've all been fixed except this one. It says I have an insufficient graphics card, which I'm pretty sure can't be the case since SV and RV work just fine. They even work fine after I add all of the lots from all of the EPs. Heck, my Immortal Dynasty (biggest file by far) doesn't ever crash because it's in Riverview and it has all of the EP lots. And in Sunset Valley and Riverview, I can set the graphics to max (with some lag) and it still doesn't crash. I normally play with only Sim Detail and Texture on max though. The rest are about medium-high. I use Twallan's Error Trap, Master Controller, Saver, Story Progression Extra & Expanded, Debug Enabler, and Overwatch. However, the crashing started before I starting using any mods, so they're definitely not the cause.
This is very frustrating, as I paid money for EA towns that I can no longer use.
I used to have Sims 3 on the DEP list, but a fellow member suggested turning DEP back on. This actually increased my frame rate, but those towns still crash (SV and RV still work fine). So DEP does nothing for me. I'll go ahead and list my computer specs and see if anyone can help me. I started having this problem sometime after Pets came out. When I first started playing in Appaloosa Plains, I never had crashing. Even when Union Cove came out, I didn't have crashing. But now I'm suddenly having it, whether it's an old save or a new game.
I swear I will write a heroic ballad for anyone who can fix my crashing.
