Luka,
This part works by increasing the voltage drop across itself until the
current is as low as its design current. Therefore, it needs the ability
to do this, which means that the device that it controls needs to be
able to respond appropriately.
A Nixie tube is a constant-voltage device, so it will have the same
voltage across it, independent of the current flowing. This means that
the Nixie tube is a very poor load for such a two-terminal
constant-current device.
I would recommend using a voltage-dropping resistor instead. It is known
to work properly.

I have spent a day or two looking for a final solution and found
something I honestly didn't know existed. Although they seem rare, there
are so called current limiting diodes (CLD) which you can pretty much
put in series with a load and they'll limit the current trough it and
keep is stable as voltage changes across them.
