Starting a new save and I wanted to try Krastorio alongside Space Age, but I can't get your tweak mods to load, both this one and the fork you made of xyrc's Enhancements. They both throw up different errors when restarting to enable the mods.
This is your tweaks:
Failed to load mods: nulls-k2so-tweaks/k2so-tweaks/util/graphics.lua:29: Primary icon does not exist
stack traceback:
[C]: in function 'assert'
nulls-k2so-tweaks/k2so-tweaks/util/graphics.lua:29: in function 'create_dual_icon'
nulls-k2so-tweaks/k2so-tweaks/patches/planets/arig.lua:13: in function 'on_data'
nulls-k2so-tweaks/k2so-tweaks/util/patch.lua:62: in function 'do_data'
nulls-k2so-tweaks/data.lua:12: in main chunk
And this is your fork of xyrc's:
Failed to load mods: xy-k2so-enhancements-nulls-fork/patches/item_weight.lua:10: attempt to index field 'sand' (a nil value)
stack traceback:
xy-k2so-enhancements-nulls-fork/patches/item_weight.lua:10: in main chunk

p.s. why does factorio not let you copy paste these error logs :'(
