<p>Dan,</p> <p>I have diagnosed the problem.&nbsp; It is not related to setting the forecast catch = 0.&nbsp; Rather it is a problem with the propagation of the forecast population agecomp from one time step to the next.&nbsp; I see how to fix it and will get a new exe posted soon.&nbsp; But I also want to hunt down when this problem got introduced.&nbsp; A similar issue occurred for another user with age at settlement = 1.&nbsp; That got fixed but now you encounter a similar problem with multiple seasons.&nbsp; Top priority now.</p> <p>Rick</p>

<p>Hi Rick, I am using the lastest version from vLab :3.30.15.</p> <p>Note that in the model, the F for fleet 6 (longline) is extremely high,&nbsp; although the the catch is very tiny. This is because the selectivity for fleet 6&nbsp;is very&nbsp; poorly estimated. But I don't think this is a separate issue and should not be&nbsp;what cause the problem as the projection&nbsp;works fine in 3.24, and the catch for all fleets are set to zero in the projection anyway.</p> <p>&nbsp;</p> <p>Thanks for helping out.</p> <p>&nbsp;</p> <p>Dan&nbsp;</p>

<p>Hi Dan,</p> <p>Sorry that you ran into a problem here, we'll take a look.&nbsp; Which version of 3.30 are you using?</p> <p>Rick</p>

<p>Dear SS3 team,</p> <p>I run into an issue with the SS3.30 (lastest) constant catch forecasting, which doesn't appear to be working.</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>Parameter estimates from the 3.30 are the same as the 3.24 (I used the ss_trans.exe for the conversion).</p> <p>Running the forecast with alternative catch levels under 3.30 had the same issue</p> <p>I have attached the input files for SS3.24 and the problem is very easy to reproduce.</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>Thanks for your help.</p> <p>Dan </p>
