Worked: 2.82a

Short description of error
In Blender 2.82 smoke/fire simulations with Adaptive Domain worked with 'OpenVDB' baked caches.
In the current nightly builds of 2.83, smoke/fire sims only work when baked with the 'Uni Cache' format. This is with cache type set to 'Final'.

Exact steps for others to reproduce the error
Open a new blend file.
Create "Quick Smoke".
Select the Smoke Domain object.
Go to the physics tab.
Turn on Fluid->Settings->Adaptive Domain
Set Fluid->Cache->Type to 'Final'
Set Fluid->Cache->Data File Format to 'OpenVDB'
Run Fluid->Cache->Bake All

The simulation will appear empty for all frames of the simulation.

Open file, bake all, play.
