I use Aslains original colored icons with Roman numerals (file="Aslains_original_colored_icons_with_Tier_Roman_TIM_1.21.1.0.7z")
In the current modpack (v1.21.1.0 #00) this file contains the wrong contour icons.
I've renamed the previous version's (1.20.1.0) file in the DL_cache as a temporary work around.
Just an fyi
