Hi again! I'm working on and element, a gas, for my mod, but I've come across a problem: every time i place my element, it dissapears instantly. i assume my mistake is in powder.h, so here is my code: {"HCL", PIXPACK(0xE01B4C), 1.0f, 0.04f * CFDS, 0.90f, 0.50f, -0.1f, 0.0f, 1.00f, 0.000f * CFDS, 0, 0, 0, 0, 0, 1, 1, SC_GAS, R_TEMP+5.0f +273.15f, 33, "Hydrogen chloride gas, dissolve in water for acid", ST_GAS, TYPE_GAS, &update_HCL}, Anyone know what is wrong? Thanks Tommig
