<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> </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).</p> <p>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> <p>Dan </p> <p> </p> <p> </p> <p> </p> <p> </p>
