Hi! I was wondering if anyone knows of a program I heard goes through your downloaded items and tells you of which items may be causing your game to crash. I heard about it from a friend (after I found out my game wasn't supposed to crash on a regular basis) but none of my searches have come up with anything and lately my game has been crashing more than it usually does.

As far as I know, there is no program which will tell you which CC is crashing your game. That's why the Game_Help:Game_Problem^wiki FAQ exists... to help you to find problems with your game.

The Clean Installer can tell you whether you have hacks installed or whether you have multiple copies of the same CC:

The Hack Conflict Detection Utility (under Sims 2 / Programs) can tell you whether you have multiple hacks which affect the same BHAV:

There may also be a tool which can tell you which of your CC is more computer-intensive, but I'd have to look that one up.

Sorry its taken me so long to respond. Thank you very much for your help!
