220.127.116.11 Could not load properties file: ./roborumble/roborumble.txt
I never ever experienced the same thing. And the code change from 18.104.22.168 is kept minimal that I couldn’t come up with whatever change could cause this to happen.
Anyway have you ever tried to have a clean install? Or maybe the path containing robocode contains some weird char that prevents robocode from processing (e.g. space, this bug is known)
