Yes. The player just notices the missing renown. What they don't notice is that SH3 writes zeroes for the patrol start date and flotilla start date as well. It's this aspect that upsets SH3Cmdr (the telltale sign being the "Invalid date to encode" error).
It's a very easy bug to avoid, if one spends a few minutes reading the GWX and/or SH3Cmdr manuals, or follows the advice spouted on this forum
ad nauseam.
