Similar but perhaps unrelated problem... for the first time since I started back on Ray Dream3D I am unable to copy an object, jump into the new instance, and make it a new master to edit. Even though the sequencer claims new masters are being created, all objects in the scene seem to be instances...no matter what object I select, the modelling window is no longer available, and deleting one object deletes the rest. Nothing is linked, nothing is grouped. The masters all have distinct names, and the instances list normally in the properties tray. I can't confirm that things worked before the patch, but I am currently trashing preferences and preparing to do a clean re-install. 8.6 platform, by the way (I know, I know. I really shouldn't expect support for less than 9x)
