Bug in question:

The mod doesn't work at all. It does "activatate", as in the mod is detected, but upon activating xray, absolutely nothing happens. I can't offer screenshots or anything. It just, doesn't happen once I activate it.

Edit: nvm turns out this mod requires I add the block(s) I wanna find; and it seems for good reason too. Anyone reading this, turn show lava to true at your own peril.

Figured it out lmao
