As per the title; when a group of objects are parented to a streamable model from a persistent model there is a high chance the objects will never be streamed in on the client again no matter how many times you leave and re-enter the radius. This appears to happen when the game has a good number of parts as just placing 3 - 6 seems to work just fine.
Green is a model that has been reparented. Blue & orange are models which were already streamable in Green’s new parent. Red is streamable in its own model just to try it out.
I’m aware having streamable objects in a persistent model even if momentarily is not ideal to begin with before anyone comments on that
