Hey guys, trying to learn new things but I can't seem to find answers at all. Have a general purpose ship right now but I want to build some new ships for my use. For example I want to build a dedicated trader and leave my combat ship somewhere. Where can I safely leave ships? In my starting area I am top rep level from trading and stuff. However gates leading to important sectors seems to have gotten destroyed somehow while I was exploring. One sector will have a gate and it leads to the correct sector but once there, there is no gate to get back anymore. Is there a way to fix the gate connections? Thanks for your help, i'm sure i'll have a lot more questions later fifa55
