Well as you can see, the requester and delivery combinators could use an update to their lower resolution models, and a fix for the shadows.
This should be a fairly simple fix, as you just need to move the HR variants code into the regular brackets. Since 2.0 there is no longer a HR variant coded in the game, so the game will just load the normal variants since these are considered HR now.
