Description
Editing a page using the RealTime Editor removes content from the page. Between the "auto-save by Realtime Session", entire paragraphs get removed. This can be seen in the page history.
Conditions under which this occurred:
- only 1 user editing the page in RealTime session
- a message that I cannot store the change because of a broken network connection appeared
- the content could be recovered by rolling back the page to a prior version
In the server logs, this error is present 6 times in the span of 3minutes. The error is associated with the page where the content of the page disappeared
