Minecraft Username: bobbysix6 Brief Description: cant dondense diorite, granite or andesite into polished diorite, polished granite or polished andesite Instructions: use condense all on these 3 blocks it wont condense them to the polished version How many times did you recreate this bug?: alot i guess Result: stays as regular granite, diorite or andesite Expected Result: should turn to polished item Evidence:
it's not a bug, because you create the item at a 1:1 ratio. Since you'll get the same number of items that you started with, you aren't condensing.
In addition to what Nicit said: while it's true that /condense is basically a special case of /craft, the same cannot be said for the other way around. There was a suggestion for adding a /craft command (which I strongly supported btw), but I don't know what happened of it
Forcing it with /cnd hand works because 4 quartz items are combined into 1 block, therefore actually reducing inventory space.
both /cnd all and /cnd hand work on quartz, while /cnd alone doesn't, because 1) quartz can be condensed indeed (4 items → 1 block) but 2) the process is irreversible (therefore you don't want to do it by mistake)
