Thanks both for the detailed report and the follow-up. I just ran into a similar issue after merging topics with calendar events and couldn’t figure out why the topic was breaking. Glad to see this is documented.

I’ll keep an eye on any PRs for this. In the meantime, disabling the plugin temporarily as a workaround is helpful to know. Let me know if there’s anything I can help test.
