In tele the clothing you wear can affect the bot, try experimenting with different clothing. What you describe sounds like there's something wrong with either settings or clothing, those are the only two things (appart from connection issues) that can cause the bot to not complete a maze (unless RS has updated recently). I'll check up on it though. Also, not responding to a comment doesn't get you banned... Nobody reported while using this bot has ever been banned. It's only happened twice since V2, in both cases the bot talked it's way out of it well, although I'm sure even if it had said nothing they would have been fine, because with RID there's nothing in the snapshot to indicate you're using a bot. Conversely if there was anything wrong that came up in the snapshot, no amount of talking would get you out of it. There will always be things it just won't understand and ignore, and there will always be real players who don't understand english or ignore people, the bot can also choose to ignore people or certain comments at times, for reasons like to avoid repeating itself for example, but none of that would lead to a ban. I'll check up on the talker before I release the next update anyway.
The next update will include a couple of minor changes in alch, and a ping system that will display both your bot's ping and server response time for the last session, in the interface. That will help people diagnose any connection problems they may have.
Also, thanks for taking advice seriously and heeding warnings about Jagex. Whether or not you doubt the credibility of that advice, it remains that nobody who took it has been banned, out of those who didn't there were only 10 bans altogether (8 of which came on the first 3 days, before we had a clear idea what was going on), and nobody at all has been banned in a long time now and I'm sure for as long as people acknowledge that Jagex visit this site and stick to advice, there will be no bans.
I'll post again when I've uploaded the new version, which I plan to complete tomorrow. Thanks
