First of all, it's quite a necro post but I will however still add this.
NEVER use the client downloaded from a servers site on that same server. It's very likely that the server has installed some kind of anti-cheat into the client they are hosting.
The last part with the hang-up that is because of a bad profile, if you make your profiles go too high in the air over a herb it will try to get to the herb by flying in a 180 degree line, which is not possible, so it will get offset by 1 degree, which will make the bot turn it around, which will repeat itself. This is how the last video happens.
So if you want it NOT to do that, go closer to the herb so it doesn't fly in a 180 degree line directly down to the herb. ?
