I noticed a graphical error with 1.3.3200.
Whenever connecting a switch to a power conduit, or a conduit to a switch, a conduit is immediately rendered on top of the switch.
Tested without mods. This occurs both inside and outside.
I expected not to see a conduit appear on top of the switch.
To reproduce, connect a switch to any length of power conduit, or place a switch and connect a conduit to it.
I tried to attach the save file, but even with 7zip it was 1186 KB, so I just attached a picture.
Thanks for the bug report, there have been issues with graphical glitches around conduits since 1.3 and the update of the rendering system and I will add this to the list of things to hopefully get addressed by the next patch.
