Also, since I’m unclear and it’s finally at a point that this information will be helpful…
Were these issues seen in your own app that uses SimEthereal, in the sim-eth-basic example, or in the sim-eth-es example?
Either way, if you use one of the examples, I’ve just updated their ModelViewState to grab the time from the TimeState instead of directly from the TimeSource. If this fixes the problem then that provides some more information.
Edit: especially regarding the ‘ghost’ issue… which sim-eth example you are using is important because they do object management completely differently.
