I had a lot of issues with this script at first. Spent the first 20-30 minutes of the trial messing with the settings getting it to work. It kept logging me out as soon as I started the script or it would do 1 inventory and then log me out. I was wanting to make Mahogany Tables. What worked for me was:
Start inside your house (build mode) next to the object you're building
Have all inventory items ready
Have an inventory of your planks (24 for me) un-noted (also have your noted planks/saw/hammer/money)
Make sure the object you're wanting to build is currently NOT built (if it is built the script cannot dismantle it at the start for some reason. It will say "no valid space to build" then logs you out).
After doing the above, the script works with the Demon Butler. It is a little slow, but it gets the job done.
I would like another trial for another full attempt if possible.
Thanks
