Hello for some reason I'm unable to craft blockus barrels all of a sudden. they were working fine on my server at the start, I was able to craft charred barrels, but recently (I haven't changed anything on my end) I went to craft more and its only giving me vanilla barrels now...what happened? I'm so confused why its not working suddenly.

Yep, not only does it make all barrel uncraftable, but it breaks any other mod that adds more barrels as well.
