[1.3.3087 x64] Power Cables not drawn when supplied

[SpaceMoth]

1. What the circumstances were.
This has been reproduced with Core Rimworld only. The issue started from the update to 1.3 onward.

2. What happened.
Once supplied, power cable segments under walls turn invisible.
The same has been seen with mods such as pipes using dubs hygiene or vanilla power expanded.

3. What you expected to happen.
Previously this would be shown with a construction box so it is clear where gaps in power yet to be build are.

4. Steps we can follow to make the bug appear on our machine.
Started a new colony with the standard start.
Unforbid the nearby starting steel.
Place a power cable under a random patch of wall that make up ruins.
Force a pawn to deliver or construct a piece. They will bring materials over to that and other nearby placed cables.
The cables will be invisible under the wall once supplied.

This one has been bothering me too. Power cables under walls are practically invisible once the blueprint turns into a building frame, after being supplied with steel. They can't be seen in the normal view nor with the power overlay. Ideally there needs to be some indication of the incomplete cable construction in the power overlay.

Thanks for the bug report.  This is a known issue and is still being worked on.  Unfortunately with the changes to the drawing system of RimWorld with the 1.3 update this has been particularly difficult to fix.
