I am playing prominence 2 and the replicator file was in the item_obliterator.json5 file as
"modern_industrialization:replicator",
I deleted it for the client side and server side and the block shows up with a crafting recipe but when you go to place it nothing happens

I don't see how this is relevant to MI really.

Its a machine from MI that has code preventing the block to be used? I looked for a while and found the code preventing the block from existing and removed it but once you get it you cant place it so i was wondering if there was code preventing the blocks function

There is no such code in MI at least.

ty for the info

Prominence 2 disables the replicator. This has nothing to do with MI
