Worked: 2.82a and previous versions
Short description of error
[Any change from the default upres value in Domain settings kills/frees the sim bake]
Exact steps for others to reproduce the error
[Bake the attached, then check 'noise'; if you then change the upres setting at all you will lose the bake, and have to re-bake before you can bake the noise pass.
I don't know if this is a fault or a feature, but it certainly isn't an improvement to the 'modular' cache workflow (if anything it's back to the old 2.79/2.8 smoke sim 'do everything at once, and if it's not what you want- do the whole thing again' type of workflow). And it's not how the upres setting behaved in 2.82a or previous incarnations of Mantaflow in Blender.
I'd say this is a great shame if it is a feature, as the ability to bake the sim, then try different upres settings was, what I previously thought was fantastic, compared to the 'old' smoke sim.
Here's the difference between 2.82a (first) and 2.83-
I also tried this in 2.9 Alpha (24th June build) and it behaves the same as 2.83 release version, i.e. not like 2.82a or previous versions.
