Issue:
Trying to remove BOP quicksand from world, though BiomeTweaker, with RTG, BOP, and Geographiccraft installed. Added following script to BiomeTweaker scripts:

myObject = forAllBiomes()
myObject.removeGeneratorBOP("quicksand")

Expected behavior: no quicksand pits spawn in world.
Actual behavior: Above script has no effect; quicksand continues to spawn in relevant biomes at a ridiculously high rate.

I tried several iterations of this, attempting to remove "quicksand" from only the desert, removing "SAND Generators", removing "lakes:quicksand". No effect with any of these scripts. I'm pretty sure I'm doing something wrong with my scripts, but I can't figure out what.

Is quicksand just impossible to remove?

Okay, sorry, I got it to work by turning off the Default RTG config setting, running a BOP world, and then running an RTG world. No clue why that worked, and not all the craziness I tried yesterday, but it worked, so...
