Updated to 1.21.2 and 1.21.3 Fixed all the issues with the new attribute format.
I believe this is the 1.14 version of the pack.
One of the original versions of the datapack. Pretty sure it is for 1.15... 1.16.x broke it, not 100% sure when.
Completely rewrote the datapack to work in 1.20.5, utilizing the new scale attribute.
Updated to 1.21 and 1.21.1
