I have recently installed ToughAsNails mod version 1.12 and the only item that I cant craft is Charcoal Filter
I have the necessary ingredients and It doesn't seem to craft
I go on a different world that is creative and I can access the item only on Creative Mode but I need help with crafting this in survival

Same here dude, Its quite annoying not being able to craft Charcoal Filters

That is weird, I"m using 3.0.0.62 and i can make filters with ppp ccc ppp.

if its fixed this can be closed, according to bob0bob it is.

has this been fixed? or still having issues

The recipe was updated but the wiki wasn't. This has been fixed now
