Being backwards compatible! SO... after having been away from the server for a very long time I found my old "mining box" (= shulker box) with a lot of raw copper in it. That just screams to be smelted, and fortunately for me I have this giant furnace which I've (re)build.... I dunno, back in 2015 or so? Originally this had regular furnaces in them but as you can see I replaced those with blast furnaces (I don't even remember doing that). You gotta hand it to both Mojang & Aikar.. stuff still works. Speaking of things that still work... and this is why I always used wool for my redstone stuff and also set up signs which explain which circuit does what. Of course... I have no idea how I managed to set any of this up anymore but at least I know what does what Good times!
Reminds me of when I had my super smelter on SMP6. I enjoyed throwing everything into it to get it mere seconds later.
