that is described in the EBR/135784
As for warping to citadels - right click on inventory or solar sysem menu expand to structures select one from list or just right click on autopilot target and 99% you see no “warp to…” if they are not on the overview. Basically anz other way then clicking on the overview fails. It just tells me silly stuff if i select dock it says “The engineering complex is too far away it must ne within 2500 M” or If i say approach "You can not navigate that way with the seleted object as it is too far away"
funny thing from 8 engineering comlexes in the list i can warp to 2 of them the rest has no warp option.
I have access to all of them just don not have them on the overview.
