OK, after a few more games testing the new PTS Patch on my HDD equipped Xbox One S, there still can be loading in problems on Miramar. Specifically if you hot-drop through the hole in the Casino ceiling in Pecado, the building and weapons will have loaded in but the interior furniture won't have.
Thanks, Rob.
