we recently noticed a Bug in our Ghost Data that led to some lost bases on PvE The Center. Please check if your base has been wrongfully removed and if so open a ticket so we can make sure you get all your stuff back. It may prove difficult to restore any bases, but we will do anything to compensate your losses. Worst case scenario will be that you get the structures and need to built up on yourself, but we will do everything to restore as much as possible.
Sorry for the inconvenience,
