I don't recall Cotton-Datapack.json5 is actually our config as CottonResources uses CottonResources.json5

This is likely an issue with the main cotton project and you should probably ask here:
https://github.com/CottonMC/Cotton

I deleted the cotton, it was master 1.0.0 not 1.15, installed that, now no errors in sight, but i still dont see the blocks in REI im using minecraft 1.15

i dont have a CottonResources.json5 in my .minecraft/config folder
