Wait I thought I fixed that when I did Mystcraft Compat ages ago?! And NEI does not display any way to get that Myst Ink Bottle?
Edit:
for (FluidStack tDye : DYE_FLUIDS[DYE_INDEX_Black]) {
RM.Mixer .addRecipe0(T, 16, 16, FL.array(tDye, FL.Water.make(125)), FL.Myst_Ink.make(500), ZL_IS);
RM.Mixer .addRecipe0(T, 16, 16, FL.array(tDye, FL.DistW.make(125)), FL.Myst_Ink.make(500), ZL_IS);
}
This Recipe produces the Mystcraft Ink Fluid. So I dont exactly know what is wrong there. It is made by mixing LIQUID black Dye with even more Water.
