I recently set up a discourse instance for testing by following the docker tutorial. Yesterday I updated it to latest beta 2.4.0.beta8 (68124caae2) and installed the latest versions of three official plugins (discourse-calendar, discourse-checklist, discourse-solved).
I played around with the calendar plugin, opened a new topic, included the calendar in my first post, all good. When I add a reply for adding events to the calendar however the system bot automatically deletes them after a very short period of time. When I restore the post, it gets deleted again.
The deletion events are recorded in the logs, but there’s no trace what triggered them. I am a bit clueless why this happens, and how to start debugging this.
