Hi not sure if you've looked into it yet, but it seems if you have both fix and light brazier options selected, the bot will attempt to fix the brazier, but since it is repaired before the XP drops, the bot will then click the repaired brazier to instead try to light it. This cancels the construction XP, and gains FM XP. I disabled the light brazier option and kept the fix option, and I am now gaining Construction XP.
This script has been amazing, but it doesn't seem to be fixing the brazier. I have the option selected, but I haven't gained any construction XP throughout 180 rounds. I am 10 Construction, with a POH.
