couldn't get module to work either.
So i just used sniffer to find npc and potion id's and typed it out myself. Not that difficult. If you would like to simplify doing it multiple times, just use the bind module. entertaining to type it:
.repeat 20 repeat 500 send 33.....
fills up area quick (once you're past the lag, which doesn't last THAT long)
But geez, those waves of gold look really cool, especially the first one, where the ground is all clear.
Also interesting, is if you leave that first layer, the "sparkle" animation has an interesting motion pattern over the field of gold.
