set_command for biters sometimes doesn't work.

[yagaodirac]

distraction = defines.distraction.by_none doesn't guarantee the biters not be distracted. Biters sometimes follow the command for 1 or 2 seconds and then get distracted.

With
some biter.set_command{type = defines.command.go_to_location, destination = somewhere, radius = 20 to 30, distraction = defines.distraction.by_none},
biters even chase players for 200 or 300 tiles. Any idea?

Without some more info to go on, I am going to assume you are just doing something wrong with your mod scripts,

I have used units a lot and never had such a problem
