Brief summary of bug

ERP_P72x2_Ld30.f45_f45_mg37.I2000Clm51FatesRs.cheyenne_intel.clm-mimicsFatesCold
has been failing at SETUP (previously as a clm50 test and as a clm51 test as of today)
with Fire emission can NOT be on when FATES is also on.
This is an EXPECTED FAILURE. I looked into it a bit and wanted to post thoughts on fixing it.

General bug information

CTSM version you are using: [output of git describe]
ctsm5.1.dev153

Does this bug cause significantly incorrect results in the model's science?
No, but it prevents testing of mimics/fates.

Configurations affected:
mimics and fates on at the same time.

Details of bug

Fixing this may require pointing the mimics testmod to /basic instead of /default to avoid setting -fire_emis; however, the fix would affect all mimics tests, so I wanted to look more carefully whether this is ok to do.

I found additional problem-solving notes for this failing test in this issue.

UPDATE:

1. The test is now ERP_P256x2_Ld30.f45_f45_mg37.I2000Clm51FatesRs.derecho_intel.clm-mimicsFatesCold
2. The test builds successfully in the ctsm5.2 branch (see Workaround for transient Smallville tests #1673 + testing all new datasets #2318)
3. We're on derecho now and the test fails at runtime with a "CH4 Conservation Error in CH4Mod during diffusion"

I would first remove the P256x2 and try again in case the error message is a "red herring."
