Possible bug report
Ok there it is RoboRunner-bugtrace.zip. Looks like i was wrong it happens straight from the start. I deleted all xml files and the output of the first run is shown in the zip file. Maybe it helps :). Let me know if you need more. i broke the run after the second season with 'CTRL-C'.
Well, i just made the melee output a little more 'eye' friendly :) but i guess i will enhance the output to something that i use in my other outputs in the next days (nothing serious just a little more info on bullet hit ratio of all bots,some movement stats, sorted output of APS and a table of all bot score to each other). Based on an early RoboRunner version i rewrote it to a console like application. So basically you start the program and use console commands to configure,run.output some stuff. Unfortunately does it not use multiple threads and i'm now back to the latest RoboRunner and maybe i can merge the two somehow.
I think if you look in GitHub at Network you should see the forks that go of of your main branch.
