Kicked off the server after passing Nexus. Nexus is missing at the Atlas point.

Hi!

It's been a week now that I've been experiencing logouts from the game server with loss of progress. It is unpleasant, but I am very often in the situation, as I myself work in support and realize that some processes do not depend on anyone in the moment. But I have a wish for the developers: add server rollback, so that you don't lose especially important progress. Just now I was kicked from the server after passing Nexus. After re-entering the server Nexus in this point of Atlas is gone, as well as two points for it. It's very frustrating.
I really like the game, but it's been a week since release, and I wish rare events like the Nexus wouldn't disappear.
