Some anti-virus programs will delete random files. You might need to check your anti-virus and see if it quarantined anything when you extracted the .rar file.

Sorry to hear that it wasn't something simple to fix. I'm not sure what the issue could be in that case...My next best guess would be perhaps it didn't extract properly and a file went missing. I have the best results with winrar or 7zip.

Bugs where they appear for no reason and then go away for no reason are always so weird...
