This is a potential fix for the Dyer. I have removed the Cactus to Cactus Paste furnace recipe and added a shapeless Cactus + Pam's Grinder recipe to replace it.
This should allow the dyer to make Green Dye with the vanilla recipe he starts with... Vanilla recipe to cook Cactus needed to be re added for this which is included.
I thought this would be a better fix than modifying the Minecolonies recipe that the Dyer's Hut starts with, but it's up to you.
I tested this in single player and it seemed fine.
A breakdown of what I did
Removed Cactus Paste furnace recipe
Added shapeless crafting recipe with Cactus and Pam's Grinder to make Cactus Paste
Re-Added vanilla furnace recipe to cook Cactus in to Green Dye to make the Dyer from MineColonies happy
