I can't diagnose a problem without seeing the error you're getting.

ERROR:
The given sprite rectangle (left_top=0x0, right_bottom=97x97) is outside the actual sprite size (left_top=0x0, right_bottom=97x41).
See the log file for more information.: RoboportTweaks/graphics/roboport-door-down.png

What seems to be happening is the HD mod makes modifications to the graphics for the roboport, which get copied over to the extender when it's defined later in the loading process. Normally this is working as intended, but having a lower resolution than the version the HD mods substitute is causing problems. I can make a patch that's going to make it look messed up if the HD mod is installed as well, but at least it'll load.

if i understand correctly, HD doesn't change the way graphics are loaded, only the graphics themselves
maybe there is a way to disable graphics loading in RT and leave it on the vanilla engine?

thanks for the update, at least it loads now.
maybe attach a picture of the vanilla hatch or leave the hatch alone and make a picture of the roboport with the lid welded on?

I just realised all I needed to completely fix the issue was a couple more lines, so I've added those, it should be fine now.

now it looks great, wonderful, thank you
