Having this mod installed adds a red circle with a line through it to some other mod's item/recipe icons, such as:
Every compress+decompress recipe in Boxing 2
Robots + Cargo wagons in Creative Mode
Thorium ore in Bob's Ores
Can confirm this as well,
It also causes all the barrelled items to have the "no" symbol (Red circle with diagonal line).
The barrels have this inheritance model: base > angelsrefining > Flare Stack
Happens with Canisters too.
