I'll priorizie this bug and finding a fix for it. What I expect it is is actually an area bug. The script has the areas programmed in but sometimes I find if your bot is one tile outside of the area it won't do any walking that its supposed to do, this doesn't happen 100% of the time though.
I will try and find a way around this and if I can't I'll talk to Patrick about it and see if he can find a solution.
As for adding the areas if you can show me exactly which areas you'd like added I'll look into these (I've never done firemaking in either of these areas so I'm not too sure where the meta spot is
