Re: What are the lastCleanException.txt files in the TS4 folder can I delete them?

@YsUniverse  Yes, you can delete those files.  They're reports of in-game errors, so they're useful for troubleshooting purposes.  For example, yours are mentioning custom content that might be corrupt or incompatible with the newest patch, and if you're having issues with your game, it may help to remove or update these files.  However, the game itself doesn't need the files to be present.
