At the moment, there is no way to detect whether or not a specific asset has actually loaded or not. The only thing we can do is wait until the RequestQueueSize is 0, and that can hault things for awhile for people who have slow internet speeds (as noted on Murder’s loading screen)
A YieldFunction version of Preload would be tremendously appreciated in this case, so we can wait for content we specifically need at the moment rather than just all of it at once.
