Safemode
As of version 2.45.03 Darwinbots will include a new 'Safemode' feature which will make crash catching easier. If you experience a crash just restart the program and follow the instructions on the screen.
Safemode works by trying to figure out at what point in the simulation the program crashed in 2,000 cycle intervals. There is a very rare chance that you will be prompted to enter diagnostic mode more then 3 times, if that happens just give the administrator the lastran.set file.
You can also use safemode to send the administrator bugs. Just send him the lastran.set and lastautosave.sim files.
Finally, you can disable safemode to improve performance by going to global settings. However, this is not recommended as there will be no way to debug the program if a crash or a bug happens.
