Plate mode bots report wrong and/or bad intersections for a given shotline. Depending on which side of the (unoriented) bot is hit, you can get a miss altogether or an incorrect segment result. Moreover, if you put a plate mode bot in front of a volume bot and nirt or rtcheck them, you will get incorrect overlaps reported and invalid nirt segments. It also looks like putting a plate mode bot in front of a volume mode bot behind it will cause it to *also* miss the volume mode bot.
This has been verified and narrowed down to the attached simple test case.
Edit plate.bot and nirt one side, then nirt the other side of the plate surface. Nirt through two of the plate surfaces at the same time. Nirt through the plate surface with the volume surface behind it but on the shotline.
