+                        support is now available! There is one important caveat... I can't figure out the exact
+                        quantities of all the various liquid-based recipes, so the numbers have been completely omitted
+                        for that part and probably are a bit incorrect. If you have any further information about those
+                        recipes, please let me know!

                         At the same time, I've changed the quantity field to allow up to 9999 of any item. Have fun with
                         those huge builds!
