An addition to my first point. A couple times someone on my server has done what he calls inventory maintenance, not sure why, but he ends up dumping all his cargo into space. Each time that consisted of a couple hundred thousand ore and every time he did this it caused massive lag spikes across the server. He says he has learned his lesson so hopefully it will not happen again. But all that additional cargo for people mining, salvaging, or peoples automining fleets is just going to be adding even more strain onto servers. Another point I hope to going the route of it not taking up cargo space at all.
A sidenote about the change. I see the logic about changing to a raw/refined types and have no issues with that. I even kind of like it if it means I can get higher percentages. But it definitely needs some refinement imo.
Thanks for a great game by the way!
