restart error: Field missing from restart file: lnfm24_VALUE

Hi Fates users,

Has anyone else received the error below in the lnd log when continuing a run (CONTINUE_RUN = TRUE)?

"ncd_inqvid: variable lnfm24_VALUE is not on dataset
ERROR: Field missing from restart file: lnfm24_VALUE
Missing fields are not allowed in branch or continue (restart) runs."

This is for a singlepoint run with the nuopc driver using ctsm5.1.dev099, cime6.0.27, and sci.1.57.4_api.24.0.0. In the user name list I have use_fates_cohort_age_tracking = .true.

The rest of the error output say's:

"This can happen when the restart file is from a different
model configuration or different code base, which did not
contain all of the restart fields needed for the current
code base and configuration.

You can get around this problem by doing a startup or hybrid run
that points to this initial condition file, instead of attempting
a branch or continue run. However, note that, in many cases,
this will result in the missing fields being filled in with
their cold start initialization values, which may or may not
be what you want."

I'm running fates api 24 with ctsm5.1.dev099 because this is listed as a compatible setup in the HLM compatibility table, but perhaps there is an incompatibility when it comes to restarts? Perhaps Fates is not writing the lnfm24_VALUE to the restart file and CTSM wants it for a restart, or vice versa? Any thoughts on how to fix it would be greatly appreciated!

Hi all,
This issue was fixed when I created a new case directory and ran with the exact same settings. I think the issue was that I was re-starting within a case directory where I had already done many different runs of varying length and namelist settings. Although I don't know exactly why this would cause an issue, it must be something related to this and that the case folder was getting too messy, perhaps making it hard for fates-clm to find the right restart file.
