[FLASH-USERS] overwriting of snapshots

[guido]

Hello Flash users,

I found out that one simulation is overwriting the last snapshot instead 
of writing new ones. I think this very strange because this did not 
happen with previous snapshots.

The code keeps writing the snapshot 9999 instead of creating the 10000 one.

The flash.par used for this simulation is the following:

# Runtime parameters for a generic problem
# check the online documentation for runtime parameter descriptions
# or look at the setup_params file in the object directory for
# descriptions of parameters specific to your simulation

Do you see anything in my flash.par that might cause this error? I'm 
using flash 4.5 by the way.

Kind Regards,
