I am on a new install, and when I attempt to use this mod, I get this on startup:

...util/graphics.lua:29: Primary icon does not exist

There is more info I can provide if desired (no way to copy paster or I would have).

My title is incorrect; It should be mod won't load, as it installs.

Here's more info (stack trace):

in function assert
util/graphics.lua:29 in function 'create_dual_icon'
patches/arig.lua:13 in function 'on_data'
util/patch.lua:62 in function 'do_data'
/data.lua:13 in main chunk

I added Aria-Carnova system, and now it loads fine.

Fixed in 1.23.1.
