Thank you for the reply rex, I/we had nothing set to public, everything was set to IEH.
Last week my core was hacked by another player and everything in my base taken, I posted in the HWS Police section and the player was punished accordingly and Achilles refunded me some materials/ores - HWS Police - not running currently
However there is a water generator outside my base that displays as ‘Wrong core or faction’ which i suspect could be glitched as ‘his’ so would this cause the problem, I left it as i wasn’t really bothered as I simply made another.
