Bases and chests lose stability

I would suggest using the appropriate topic depending on your issue:

  1. Placeables/chest losing stability and/or decaying. This one is acknowledged and being worked on.
  1. Whole bases disappearing, I don’t think this is something that has been confirmed as a bug. It might help providing more details in this thread and submitting a ticket to ZenDesk if it happened on an official server as they can check the logs and your account:
