I just looked at some of the issues I had setup on my freighter in a test save. Some of the issues appear fixed, but certainly not all of them.
Here is what appears to be fixed after a quick look:
Green Coloured Light now powered by default, where it would previously remain unpowered.
Large Hydroponic Tray now appears to be powered when placed right in the middle of 4 large freighter rooms.
Below shows some of the remaining issues that do not appear to have been fixed:
Fleet Command Room still has several edge cases where power does not reach.
Curved Corridor still has power issues towards the end where connecting to other rooms/halls
Still seeing lack of power between two connected large rooms
Once the MBINCompiler has updated I will investigate to see if I can find what has actually changed to fix the large trays and green light. I will likely still be able to reproduce the other remaining issues as I did before, which would disappoint me.
I know we are not able to use logic on a freighter without mods or tools, but I truly hope they will not ruin that as well, by making everything powered.
