Osmiridic production template makes liquid with 5 PU in 528 mode.

But SILEX accepts solution with no PU

So it is impossible to transfer osmiridic solution by ducts.
Only one way to produce osmiridium - picking it by hazardous material tank and putting it into SILEX by hands.

And it is impossible to produce osmiridic solution in chemical factory (it has no tanks slots)

The way with hazardous tanks no more works.

I changed chemical plant config. It is solution for problem. But in default it is what it is.
