Thats very minor issue, but it looks like SS mech and normal German mech getting different sprites after 2nd 'visual upgrade' of unit.
In older versions they looked the same all the way, so I don't think it was intended.

This is intended. I think it was done because the first old mech image was moved to motorised unit so we had to reduce the number of different mech images. That meant one German mech image type wasn't being used anymore. So it was decided that the SS mech got that image while the regular mech got the standard image.

Thats still working somewhat strange, as I have 3 SS mech units (tech level 17 all) in my game - 2 of them have same image as normal mech, only 3rd one has that old image.
3rd one is actually Wiking unit, maybe thats special image just for it?
