The logic way: Why the bot can move faster Or Why the bot can't keep a bigger distance?
solution:
1) Because of lag(not yours, the host's).Supern00b as u said :a time worked now doesnt (the host started torrents

)
2)The c++/c# algorithm.I know that Ibot have the option called Radius. BB has a prewritten one, u can't set it as u like.
Hope some1 fform BB development team will read this !!
