Ok, I created a temporary revision of DB2.46.01 to figure out this bug.
Please follow the following steps exactly so I can figure out what is going on:
Step1, Move Darwin2.46.01Temporary to your normal darwinbots folder.
Step2, Go into global settings and enable 'normalize default mutation rates'
Step3, Restart Darwinbots
Step4, Add a robot (the one you have problems with) and make sure to copy it's exact location (I need that to figure out what is wrong, please give location to me)
Step5, Open mutation rates and press default rates, you should see a message.
Step6, Press Ctrl+C on that message to copy it please paste it here.
Step7, Close the window or press OK. You should see a message
Step8, Press Ctrl+C on that message to copy it please paste it here.
At this point the program should crash.
Thank you for your time and help.
