Since the streamer keeps creating textlabels after leaving the area and returning, the handles change and when those are sent to the client, labels on the client get replaced or overwritten since the handles (ids) on the client are out of sync with those on the server. So subsequently, this causes 3D text labels to disappear. Hopefully, this could be fixed by letting the client be aware of the label server handles in some way.
