In my crafting manager with buffer chest, I tried adding the fuzzy upgrade on a crafting module, which it accepts. Let's say for chests, any planks can make chests. So, I set the oreDict option on the input planks in the recipe, and this works fine, it imports any planks that are available that meet the oreDict reference. However, it will not send them to the satelite pipe from the buffer chest *unless it matches the exact item in the input from the recipe, regardless of whether it meets the oreDict reference or not.

Here is my set up: https://imgur.com/a/LQKD7CV

Specifically, I am using any ironOre variant in Gregtech to make Dense Iron Ore. It imports any oreDict item, but will only send the original iron ore to the satelite pipe.

Note that although in some cases fuzzy works. It's mostly broken in current logisticspipes, i'd recommend not using fuzzy upgrades with oredic/meta etc whatsoever or you will get some very weird results.
