So, I'm facing AWAY from the base that I didn't realize was a POB (I thought it was Beaumont BASE, not Beaumont SPIRE). I'm trying to see what mount does what. When I fire weapons AWAY from the base the damn system decides to fire the rear turrets in completely the opposite directly from where I'm aiming, and the base immediately goes hostile.
Don't worry, happens to everyone. You did no damage to it ( other than spending few units of fuel for the shield ), and your reputation towards the base will get fixed on the next server restart.
So just check it again tomorrow and it'l be dockable again.
