i don't think this is true for generic cases. if you have some fully async threads running, then it might be a problem. otherwise, it is well-defined behavior. Perhaps you have a specific use case or example that illustrates the issue?

When you checkpoint a running sim without freezing and reload that checkpoint, the data recording log resumes on the next frame. So far that's the most glaring thing I've found, but I'll keep looking.
