If FLASH4 either doesn't set that parameter anymore or had conditional
parameter setting, that will need to be taken into account in the
future.  I've checked and it looks like this parameter is optional (it
will default to L0) and so I've added a check for it.  If it's not
present, it sets it to be the most lenient.  This was done in the
current development branch, in changeset 2ace6373d8a3, so you will
need to update with "yt update".

Thanks,

Matt
