Thank you for your swift reply. I think that the main point from your reply is to run it in fixed mode. That appears to fix the majority of the issues I was having. I was selecting the ores (not depleted) in the mining guild yesterday and it was simply not selecting them. So I tried it in non-selection mode and it kept trying to take an ore from another player - making the bot never try to mine an ore that someone else is mining might be a good addition. I have not tried the bot at Varrock West again since changing to fixed, but the walk pathing seems fine in the mining guild so it's probably fine in Varrock.
