As we reported on Monday, another fire broke out on Monday morning on the roof of a building undergoing repairs.
Authorities say careless smoking caused the blaze, which took firefighters an hour to get under control.
No criminal charges are pending.
While there was some damage, the structure of the building was not compromised.
This is the second studio fire the studio has endured. On May 1, more than 100 firefighters battled a nasty fire that ripped through sets. The cause of the fire was not determined as the flames destroyed all evidence of the source.
