Numerical problem size limit - persistent error message - please fix

In 2020 R1 mechanical. If you change your mesh and exceed the 32k node limit, an error message tells you the solver cannot proceed (fine).

You then change the mesh sizing to reduce the number of nodes below the 32k limit; click solve; but the same error message persists.

The only way to fix this seems to be to delete the analysis in Workbench and create a new one.

Please can you fix this? It's infuriating that all my time spent setting up an analysis is lost, if I adjust the mesh sizing and accidentally go over the 32k limit, and have to set up the analysis completely again.

There's a node count option somewhere in Mechanical.  Basically, the solver counts the cell/node ID for the checks, resetting this should resolve the issue.
