Have used this bot with alot of things, slayer, farming etc.. usually use it for about 2 hours at a time and never really had any major problems.
Buggs out now and again where it will move out of range of the set location then just stop attacking but this is very rare.. also a few occasions where it wont loot properly e.g not picking up untradeables and not picking up items over the set value.
Bot also has a big problem with picking up runes, Nature, Death etc.. ive tried many ways but i can ever get it to pick up runes.
