We're currently encountering a rather unpredictable bug with POBs.
In the case of it, sadly frequently, happening, POBs will be set to a mining event mode.
In this mode, the station will not become hostile when shot, nor will it raise its shields.
Additionally there seems to be an issue with some POBs not repairing at all, consuming resources without replenishing their health pool.
So for the time being POBs may not be attacked by players nor may new bases be constructed(the construction is prevented by requiring an unobtainable commodity)
All attack declarations will be valid again once the bug is fixed.
