Just randomly during a live server, this function call just stopped working. Like at the Start of the server it worked, and loaded in a Stadium Model from my inventory. But, about an hour later, when it was time to switch out the Stadium, The function just returned a Model with no children, and is doing this for all my Servers currently atm.
Working on resolving this. Sorry about the problem; looks like there was some change that intended to fix free model insertion on RCC in some cases but instead broke private models.
