cool high voltage generator

You miss the point, '0' is not "ground", it is "global common", and has no business being used within a subcircuit. If something in a subcircuit should connect to true circuit ground, it should come out on a pin (and NOT be named '0'). Subcircuits that mistakenly use '0' will produce bizarre results if not powered (Vcc,Vee) conventionally.

Disclaimer: On occasion I will "sit" an otherwise floating piece of behavioral math on '0', but it has no effect on any subcircuit pin current flow. This is _not_ a method for amateurs.

You're posting almost everything you do now-a-days as an LTspice schematic, then ignoring any flaws the simulation tells you >:-} ...Jim Thompson

Yes, the flux is fixed, so if the current path changes then the inductance changes, so the actual current flowing must change to compensate. Took me a while to wrap my brain around it.

Spice doesn't know how to deal with persistent currents.

Can't you charge up an inductor and then short it?

That simple circuit probably works, but when you include a bit more of reality, you get stuff like:

"Voltage source and/or inductor loop involving L_L2 You may break the loop by adding a series resistance"

Guffaw!

Maybe this is the problem...

.model Rnoise RES(T_abs=0) .model pmod pjf (beta=0.5e-2, T_abs=-10) .MODEL DX D (T_abs=0) .model dn d(kf=2e-12,af=1, T_abs=-4)

Note the temperatures ;-) ...Jim Thompson

That behavior was a red flag for wrong pin order in the subcircuit call.

Two lines if behavioral math passes load current to proper rail:
