What I suggest that once the servers are reset the custom smelting for skyblock (not sure if it's on grid/survival or not) is changed from cobble -> stone -> sand -> glass to: Cobble Stone Smooth Stone (the block being added to creative inventory in 1.13 and then survival in 1.14 by smelting normal stone) Gravel Sand Glass Why Firstly, adding in the smoothstone step will futureproof any contraptions made as it means that once we update to 1.14 the smelting stays the same. Secondly, it's a cool block with a nice texture and I think it should be made available in 1.13 as well as 1.14 when it becomes available normally. Finally, gravel will become much easier to obtain to craft concrete, as growing the trees in the nether is a big pain because the glowstone takes a long time to mine. Positive - Server will be futureproofed - Extra blocks for us to use - Easier method to get concrete (just includes lots of smelting rather than trees in nether) Negative Getting glass from cobble will now use 5 coal rather than 3, however this may cause an increase in price which will be good for the economy. How However the custom recipes are currently implemented from stone to sand, I'm sure there's a way to edit that to add in some extra steps.
