Yeah i think this might be my rubbish search algorithm. Instead of looking for the cereal nearest to the bot it looks nearest to the center of its search area. It's on my to-do list to fix. Thanks!
i already notice that when my bots try to build new fences and after that i discovered the beacons. i just grin at that logic and spread out some beacons and all is fine. let that code in for the first two bot types and call it a feature and the next gen. becomes then a more logically ai code. x'D
