I've noticed a LOT of improvements just since last week. Few issues I still have:
#1 - The Anvil issue folks are describing. The bot's brain just seems to explode. FPS lags to almost nothing. I'd suggest that now that Profession CDs are handled just before the mine that maybe just using the anvil at the mine entrance is a good idea - at least until the other logic gets more polished.
#2 - Got stuck in a loop on my L3 mine due to a couple nodes that were left up in the very back of the 3rd vein.
#3 - In order to run the bot successfully, I have to close it and then reopen it for each individual toon. Doesn't stop it from working, but a bit of a pain if I'd rather babysit it than use relogger.
Like I said - really good progress from last week, though
