I purchased this yesterday, sometime it may work decently for about an hour or two, but sometimes it keeps messing up. I'm using the demon butler option doing oak larders, if the butler comes back when you don't have a full inventory free, it will say you only have some space; you either then have the option to "bank the rest" or another option, cannot remember what the option was (not doing construction at the moment)
However if you could get the bot to select the second option on this dialogue menu, that'll allow the script to run a lot more flawlessly, as that's the only thing I can see causing a massive hiccup.
As when that specific dialogue box comes up, the bot does not do anything.
