This flower gen code make a lot of errors when you try to make a new world. Not sure why is do's this:
for(int j=0;j<1;j++){
int XcoordGeneFlower = blockX + random.nextInt(16);
int ZcroodGeneFlower = blockZ + random.nextInt(16);
int YcoordGeneFlower = random.nextInt(256);
(new WorldGenFlowers(sciencecraft.sciencecraftGeneFlower.blockID)).generate(world,random,XcoordGeneFlower,YcoordGeneFlower,ZcroodGeneFlower);
}
and here are all the errors it gives (it is a bit)
