I bought the elite package and this script is included. I'm about 12 hours deep and like 2m xp. The xp/hr is very reasonable but coooould be better but not worth complaining over, I'm satisfied. My only two suggestions for improvements would be giving the script a better reaction time to the brazier breaking - I've never ONCE gotten a construction XP drop from repairing it (despite having 20 construction and a hammer in the invie... people just fix it too fast even with my character standing at the brazier. The script doesn't react fast enough to click it. 2nd suggestion is that if a stop is scheduled (a break / timer to stop / stop after round etc) that the script actually knows to make sure you exited the game or properly logged out. I found my HC sitting at literally 1 HP mid game with the script off because I scheduled it to stop after an hour lol. Probably 2 ticks away from dying but that's user error. I did manage to save myself just in time.
Quick edit - Yes I did check the box to repair brazier in the settings.
