Your simulation starts on step 5 million from a restart file.
If you want fix ave/time to do output every 2 million
steps, then it can't produce output on step 6 million,
b/c it doesn't have data from steps 4m to 6m.
But if you use fix ave/time every 1 million, then
it can produce output on step 6 million.
Am I missing something here?
