all deez

PacketPlayOutWorldParticles o = new PacketPlayOutWorldParticles(particleEffect.effect, false, (float) location.getX(),
                        (float) location.getY(), (float) location.getZ(), osX, osY, osZ, data.asFloat(), qty.asInt());

should be


PacketPlayOutWorldParticles o = new PacketPlayOutWorldParticles(particleEffect.effect, true, (float) location.getX(),
                        (float) location.getY(), (float) location.getZ(), osX, osY, osZ, data.asFloat(), qty.asInt());

the boolean controls whether or not it should render beyond 16 blocks
can you pls add :D
