<p>I run into an issue with the SS3.30 (lastest) constant catch
forecasting, which doesn't appear to be working.</p>
<p> </p>
<p>I simply set up a 10-year forecast with catch set to zero for all
fleets. The SS3.24 forecast works as intended which shows SSB rapidly
increasing (see attached SS3.24-forecast.png).<br /> But the forecast
for SS3.30 files failed - the SSB crashed a few years into the
projection period (see attached SS3.30-forecast.png).</p>
<p> </p>
<p>Parameter estimates from the 3.30 are the same as the 3.24 (I used
the ss_trans.exe for the conversion).</p>
<p> </p>
<p>Running the forecast with alternative catch levels under 3.30 had the
same issue</p>
<p> </p>
<p>I have attached the input files for SS3.24 and the problem is very
easy to reproduce.</p>
<p> </p>
<p>Hope you could help me look into this issue - (Most likely I have
missed some configuration in the 3.30 forecast file?)</p>
<p> </p>
<p>Thanks for your help.</p>
<p> </p>
