OK, I have replicated this and I have a pretty good sense of what the issue is. Thank you for the good test case and the report. It isn’t going to be an easy fix, so I can’t guarantee it will be in the next update, although that is a goal. In the meantime, I believe you can work around this by passing the same instance of your OELanguageModelGenerator to your subviews rather than re-instantiating it.
