Ok so i guess i wont get the grids back. Thats like an invitation for us try a more ‘forgiving’ server, as im still sure this wasnt our fault.
Just to sumarize:
Grid cores - 2-14 days on all grids
Power - enough for a few weeks (4x mk2 large coal reactors, 2x regular large coal reactors with a few hundred K refined coal, 3x large batteries charged, 2 small uranium reactors, some methane engines)
Safe zones checked before logging out, grinding disabled, no connectors outside the zone
No grids outside the zone
