Well I have a unique instance of find & replace that I want to use in BYOND.
I want to make it so once it find instance X it will replace it with instance Y and instance X, basically effectively adding instance Y to the square. Is there a way to quickly do this on large maps? I know I can probably edit the map through notepad & add instance Y to the list of things to the square but is there a way through the actual interface, I tried using instance Y, instance X but that just makes it replace with the second thing never adding the first.
