There seems to be something seriously flawed (again) with orthophoto.
As I mentioned before, I use orthoboxes from existing orhtos and then adjust them in size so that they keep their orientation (yaw, pitch, roll). Now there seems to be a new bug that sometimes confuses sides of the box. At random points (probably after working in ortho mode for a while), all of a sudden when I adjust and select a different side, then instead of the new side being rendered properly, it will either happen that the new side will be rendered but with the dimensions of the old one or the other way round. Intriguinlgy, this is visible in the ortho box after rendering - two sides are now orange! Also, it shows in the overall pixel size (Width and Height) when I enter a new ortho pixel size - when I do that and press Enter, then the pixel numbers start going back and forth between the correct and the wrong number twice over. I know this sounds crazy but it really is what happens. I can apparently break the cycle by switching orthophoto mode off and on again…
