Edit 2017/10/28: I've submitted a MR on mkcal to allow time restricted loading of local incidences. This will avoid to report erroneous remote deletions leading to actual local deletions. But as a side effect, it will also block the upload of new events outside the sync window.

I've created a MER bug for this. I know the reason and will try to find a solution in the coming weeks.

In a nutshell:

• any new local event is send to the server during a sync process, even outside the sync window. It then receives a etag and a URI. It is then considered shared between local and remote. The event appears then on server and locally.
• during a later sync process, the plugin is fetching data from server within a given time frame. Any shared event that are not appearing in this list is considered as remotely deleted. Thus, the plugin is removing the local copies -> failure!

The solution is then to consider also a time-restricted of local event when doing the comparison with fetched data. But it is not as easy as that from the mkCal API point of view.
