Hey,
So I've used this for the 24 hours and runs pretty nicely. There's only two things that I would say make this a little less efficient.
If you're dropping logs & keeping nests you have to manually bank the nests otherwise you will remain logged in & attempting to cut with a full inventory which looks suspicious . To prevent this I'd suggest webwalking to the nearest bank & have an option on the settings that states "Bank nests when full"
Doesn't support Castle Wars teak trees or Soul Wars teak trees (These are usually the recommended locations for teaks to 99) this could easily be done by using ring of dueling to castle wars for better banking and would also solve #1 issue.
All-in-All very nice script.
